Subject: block_rsv_check EAGAIN vs ENOSPC...
Date: Tue, 24 Apr 2012 23:50:24 +0800 [thread overview]
Message-ID: <CAMVG2stv_CbF=-A=yS40_Q6N5+_fpc2SSJxL3Rga0LQXpc8MSA@mail.gmail.com> (raw)
With 3.4-rc4 under certain workloads, I see btrfs_block_rsv_check
return -ENOSPC.
Since btrfs_block_rsv_check can only return -ENOSPC or 0,
relocation.c:3816 checks for -EAGAIN, which is either redundant or
should be -ENOSPC, which I initially suspected.
Let me know which the behaviour should be and I'll get a patch tested and sent.
Thanks,
Daniel
