From cc9939508a0693d656c52bce4b956fd8c1a96b94 Mon Sep 17 00:00:00 2001 From: Justin Maggard Date: Thu, 20 Feb 2014 08:48:07 -0800 Subject: [PATCH] btrfs: wake up transaction thread upon remount Now that we can adjust the commit interval with a remount, we need to wake up the transaction thread or else he will continue to sleep until the previous transaction interval has elapsed before waking up. So, if we go from a large commit interval to something smaller, the transaction thread will not wake up until the large interval has expired. This also causes the cleaner thread to stay sleeping, since it gets woken up by the transaction thread. Fix it by simply waking up the transaction thread during a remount.
