mutex. On the other hand, raid5_quiesce is called with reconfig_mutex hold. The first step of raid5_quiesce() is waitting for all IO finish, hence waitting for reclaim thread, while reclaim thread is calling this function and waitting for reconfig mutex. So there is a deadlock. We workaround this issue with a trylock. The downside of the solution is we could miss discard if we can't take reconfig mutex. But this should happen rarely (mainly in raid array stop), so miss discard shouldn't be a big problem. Cc: NeilBrown <neilb@suse.com> Signed-off-by: Shaohua Li <shli@fb.com>
