Btrfs: eliminate races in worker stopping code
The current implementation of worker threads in Btrfs has races in
worker stopping code, which cause all kinds of panics and lockups when
running btrfs/011 xfstest in a loop. The problem is that
btrfs_stop_workers is unsynchronized with respect to check_idle_worker,
check_busy_worker and __btrfs_start_workers.
E.g., check_idle_worker race flow:
btrfs_stop_workers(): check_idle_worker(aworker):
- grabs the lock
- splices the idle list into the
working list
- removes the first worker from the
working list
- releases the lock to wait for
its kthread's completion
- grabs the lock
- if aworker is on the working list,
moves aworker from the working list
to the idle list
- releases the lock
- grabs the lock
- puts the worker
- removes the second worker from the
working list
......
btrfs_stop_workers returns, aworker is on the idle list
FS is umounted, memory is freed
......
aworker is waken up, fireworks ensue
With this applied, I wasn't able to trigger the problem in 48 hours,
whereas previously I could reliably reproduce at least one of these
races within an hour.

Btrfs: fix crash of compressed writes
The crash[1] is found by xfstests/generic/208 with "-o compress",
it's not reproduced everytime, but it does panic.
The bug is quite interesting, it's actually introduced by a recent commit
(c6cd6e45daacc30720cf9dabe66eb094c8e9299a,
Btrfs: actually limit the size of delalloc range).
Btrfs implements delay allocation, so during writeback, we
(1) get a page A and lock it
(2) search the state tree for delalloc bytes and lock all pages within the range
(3) process the delalloc range, including find disk space and create
ordered extent and so on.
(4) submit the page A.
It runs well in normal cases, but if we're in a racy case, eg.
buffered compressed writes and aio-dio writes,
sometimes we may fail to lock all pages in the 'delalloc' range,
in which case, we need to fall back to search the state tree again with
a smaller range limit(max_bytes = PAGE_CACHE_SIZE - offset).
The mentioned commit has a side effect, that is, in the fallback case,
we can find delalloc bytes before the index of the page we already have locked,
so we're in the case of (delalloc_end <= *start) and return with (found > 0).
This ends with not locking delalloc pages but making ->writepage still
process them, and the crash happens.
This fixes it by just thinking that we find nothing and returning to caller
as the caller knows how to deal with it properly.

Btrfs: fix transid verify errors when recovering log tree
If we crash with a log, remount and recover that log, and then crash before we
can commit another transaction we will get transid verify errors on the next
mount. This is because we were not zero'ing out the log when we committed the
transaction after recovery. This is ok as long as we commit another transaction
at some point in the future, but if you abort or something else goes wrong you
can end up in this weird state because the recovery stuff says that the tree log
should have a generation+1 of the super generation, which won't be the case of
the transaction that was started for recovery. Fix this by removing the check
and _always_ zero out the log portion of the super when we commit a transaction.
This fixes the transid verify issues I was seeing with my force errors tests.

xfs: dirent dtype presence is dependent on directory magic numbers
The determination of whether a directory entry contains a dtype
field originally was dependent on the filesystem having CRCs
enabled. This meant that the format for dtype beign enabled could be
determined by checking the directory block magic number rather than
doing a feature bit check. This was useful in that it meant that we
didn't need to pass a struct xfs_mount around to functions that
were already supplied with a directory block header.
Unfortunately, the introduction of dtype fields into the v4
structure via a feature bit meant this "use the directory block
magic number" method of discriminating the dirent entry sizes is
broken. Hence we need to convert the places that use magic number
checks to use feature bit checks so that they work correctly and not
by chance.
The current code works on v4 filesystems only because the dirent
size roundup covers the extra byte needed by the dtype field in the
places where this problem occurs.

staging: comedi: ni_65xx: (bug fix) confine insn_bits to one subdevice
The `insn_bits` handler `ni_65xx_dio_insn_bits()` has a `for` loop that
currently writes (optionally) and reads back up to 5 "ports" consisting
of 8 channels each. It reads up to 32 1-bit channels but can only read
and write a whole port at once - it needs to handle up to 5 ports as the
first channel it reads might not be aligned on a port boundary. It
breaks out of the loop early if the next port it handles is beyond the
final port on the card. It also breaks out early on the 5th port in the
loop if the first channel was aligned. Unfortunately, it doesn't check
that the current port it is dealing with belongs to the comedi subdevice

Redo the `for` loop to terminate after the final port belonging to the
subdevice, changing the loop variable in the process to simplify things
a bit. The `for` loop could now try and handle more than 5 ports if the
subdevice has more than 40 channels, but the test `if (bitshift >= 32)`
ensures it will break out early after 4 or 5 ports (depending on whether
the first channel is aligned on a port boundary). (`bitshift` will be
between -7 and 7 inclusive on the first iteration, increasing by 8 for
each subsequent operation.)
iscsi-target; Allow an extra tag_num / 2 number of percpu_ida tags
This patch bumps the default number of tags allocated per session by
iscsi-target via transport_alloc_session_tags() -> percpu_ida_init()
by another (tag_num / 2).
This is done to take into account the tags waiting to be acknowledged
and released in iscsit_ack_from_expstatsn(), but who's number are not
directly limited by the CmdSN Window queue_depth being enforced by
the target.
Using a larger value here is also useful to prevent percpu_ida_alloc()
from having to steal tags from other CPUs when no tags are available
on the local CPU, while waiting for unacknowledged tags to be released.

iscsi-target: Perform release of acknowledged tags from RX context
This patch converts iscsit_ack_from_expstatsn() to populate a local
ack_list of commands, and call iscsit_free_cmd() directly from RX
thread context, instead of using iscsit_add_cmd_to_immediate_queue()
to queue the acknowledged commands to be released from TX thread
context.
It is helpful to release the acknowledge commands as quickly as
possible, along with the associated percpu_ida tags, in order to
prevent percpu_ida_alloc() from having to steal tags from other
CPUs while waiting for iscsit_free_cmd() to happen from TX thread
context.

This patch defines HAVE_BOOTMEM_INFO_NODE for ppc and adds the call to

This also adds a stub for register_page_bootmem_memmap to allow ppc to build

properly mapped.

x86/simplefb: Mark framebuffer mem-resources as IORESOURCE_BUSY to avoid bootup warning
IORESOURCE_BUSY is used to mark temporary driver mem-resources
instead of global regions. This suppresses warnings if regions
overlap with a region marked as BUSY.
This was always the case for VESA/VGA/EFI framebuffer regions so
do the same for simplefb regions. The reason we do this is to
allow device handover to real GPU drivers like
i915/radeon/nouveau which get the same regions via PCI BARs.
Maybe at some point we will be able to unregister platform
devices properly during the handover. In this case the simplefb
region would get removed before the new region is created.
However, this is currently not the case and would require rather
huge changes in remove_conflicting_framebuffers(). Add the BUSY
marker now and try to eventually rewrite the handover for a next release.
Also see kernel/resource.c for more information:
/*
* if a resource is "BUSY", it's not a hardware resource
* but a driver mapping of such a resource; we don't want
* to warn for those; some drivers legitimately map only
* partial hardware resources. (example: vesafb)

This suppresses warnings like:

sparc: fix MSI build failure on Sparc32
Commit bdf5c418f9 ('PCI: remove ARCH_SUPPORTS_MSI kconfig option')
removes the ARCH_SUPPORTS_MSI Kconfig option that allowed
architectures to indicate whether they support PCI MSI or not. Now,
PCI MSI support can be compiled in on any architecture thanks to the
use of weak functions thanks to 52ed62c813ac ('PCI: use weak functions
for MSI arch-specific functions').
So, architecture specific code is now responsible to ensure that its
PCI MSI code builds in all cases, or be appropriately conditionally
compiled.
On Sparc, the MSI support is only provided for Sparc64, so the
ARCH_SUPPORTS_MSI kconfig option was only selected for SPARC64, and
not for the Sparc architecture as a whole. Therefore, removing
ARCH_SUPPORTS_MSI broke Sparc32 configurations with CONFIG_PCI_MSI=y,
because the Sparc-specific MSI code is not designed to be built on
Sparc32.
To solve this, this commit ensures that the Sparc MSI code is only
built on Sparc64. This is done thanks to a new Kconfig Makefile helper
option SPARC64_PCI_MSI, modeled after the existing SPARC64_PCI. The
SPARC64_PCI_MSI option is an hidden option that is true when both
Sparc64 PCI support is enabled and MSI is enabled. The
arch/sparc/kernel/pci_msi.c file is now only built when
SPARC64_PCI_MSI is true.
