Hi all,

Processes are stuck at xlog_grant_head_wait() when I ran a heavy stress
test (xfstests, ltpstress and fsstress concurrently) on linux-next
(3.15.0-rc4-next-20140506) kernel.
I got the crash dump, then I think this problem is similar as a problem
fixed by the following commit.

Already fixed in the for-next branch.

49abc3a xfs: truncate_setsize should be outside transactions

Oh good! thank you!
