If anyone has any objections, please let me know. ------------------ From: Su Yue [ Upstream commit 276c61385f6bc3223a5ecd307cf4aba2dfbb9a31 ] While running fstests generic/329, the kernel workqueue quota_release_workfn is dead looping in calling ocfs2_release_dquot(). The ocfs2 state is already readonly but ocfs2_release_dquot wants to start a transaction but fails and returns. ===================================================================== [ 2918.123602 ][ T275 ] On-disk corruption discovered. Please run fsck.ocfs2 once the filesystem is unmounted. [ 2918.124034 ][ T275 ] (kworker/u135:1,275,11):ocfs2_release_dquot:765 ERROR: status = -30 [ 2918.124452 ][ T275 ] (kworker/u135:1,275,11):ocfs2_release_dquot:795 ERROR: status = -30 [ 2918.124883 ][ T275 ] (kworker/u135:1,275,11):ocfs2_start_trans:357 ERROR: status = -30 [ 2918.125276 ][ T275 ] OCFS2: abort (device dm-0): ocfs2_start_trans: Detected aborted journal [ 2918.125710 ][ T275 ] On-disk corruption discovered. Please run fsck.ocfs2 once the filesystem is unmounted. ===================================================================== ocfs2_release_dquot() is much like dquot_release(), which is called by ext4 to handle similar situation. So here fix it by marking the dquot as inactive like what dquot_release() does.
