Subject: afs: Show volume name in /proc/net/afs/<cell>/volumes
X-Git-Tag: baikal/mips/sdk5.9~14718^2
X-Git-Url: https://git.baikalelectronics.ru/sdk/?a=commitdiff_plain;h=f27fe43c808781f950641b53e3b0ca1501c6fb53;p=kernel.git

afs: Show volume name in /proc/net/afs/<cell>/volumes

Show the name of each volume in /proc/net/afs/<cell>/volumes to make it
easier to work out the name corresponding to a volume ID.  This makes it
easier to work out which mounts in /proc/mounts correspond to which volume
ID.
