Hi Jan, I'm hitting the following warning on a 4.0 kernel: WARNING: CPU: 15 PID: 1005611 at fs/ext4/inode.c:233 ext4_evict_inode+0x4be/0x4d0() CPU: 15 PID: 1005611 Comm: rocksdb:bg0 Not tainted 4.0.9-60_fbk10_rc1_3974_g796b9b6 #1 Call Trace: [<ffffffff8176af8e>] dump_stack+0x4d/0x63 [<ffffffff8106c4dc>] warn_slowpath_common+0x8c/0xd0 [<ffffffff8106c5da>] warn_slowpath_null+0x1a/0x20 [<ffffffff81242c0e>] ext4_evict_inode+0x4be/0x4d0 [<ffffffff811d248b>] evict+0xbb/0x190 [<ffffffff811d2d6d>] iput+0x17d/0x1e0 [<ffffffff811ce0e0>] __dentry_kill+0x190/0x1e0 [<ffffffff811ce2d1>] dput+0x1a1/0x1f0 [<ffffffff811b952a>] __fput+0x17a/0x210 [<ffffffff811b960e>] ____fput+0xe/0x10 [<ffffffff81086dbf>] task_work_run+0xbf/0x100 [<ffffffff81002bcc>] do_notify_resume+0x7c/0x90 [<ffffffff81771529>] int_signal+0x12/0x17 Commit 822dbba ("ext4: fix warning in ext4_evict_inode()") proportedly fixed this in 3.11. The check was entirely removed in 4.6. Is it interesting to you that this triggers on 4.0? I can revert 600be30 and see if I can reproduce it on upstream, but since the check got removed I was wondering if there was post-4.0 work that makes it obsolete?
