One possible corruption came from: [ 90.400500] list_del corruption. prev->next should be ffffffed1f566208, but was (null) [ 90.675349] Call trace: [ 90.677869] __list_del_entry_valid+0x94/0xb4 [ 90.682351] remove_dirty_inode+0xac/0x114 [ 90.686563] __f2fs_write_data_pages+0x6a8/0x6c8 [ 90.691302] f2fs_write_data_pages+0x40/0x4c [ 90.695695] do_writepages+0x80/0xf0 [ 90.699372] __writeback_single_inode+0xdc/0x4ac [ 90.704113] writeback_sb_inodes+0x280/0x440 [ 90.708501] wb_writeback+0x1b8/0x3d0 [ 90.712267] wb_workfn+0x1a8/0x4d4 [ 90.715765] process_one_work+0x1c0/0x3d4 [ 90.719883] worker_thread+0x224/0x344 [ 90.723739] kthread+0x120/0x130 [ 90.727055] ret_from_fork+0x10/0x18 Reported-by: Sahitya Tummala <stummala@codeaurora.org> Reviewed-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>
