Chao Yu 0f3311a8c2 f2fs: fix to update dirty page count correctly ... Once we failed to merge inline data into inode page during flushing inline inode, we will skip invoking inode_dec_dirty_pages, which makes dirty page count incorrect, result in panic in ->evict_inode, Fix it. ------------[ cut here ]------------ kernel BUG at /home/yuchao/git/devf2fs/inode.c:336! invalid opcode: 0000 [#1] PREEMPT SMP CPU: 3 PID: 10004 Comm: umount Tainted: G O 4.6.0-rc5+ #17 Hardware name: innotek GmbH VirtualBox/VirtualBox, BIOS VirtualBox 12/01/2006 task: f0c33000 ti: c5212000 task.ti: c5212000 EIP: 0060:[<f89aacb5>] EFLAGS: 00010202 CPU: 3 EIP is at f2fs_evict_inode+0x85/0x490 [f2fs] EAX: 00000001 EBX: c4529ea0 ECX: 00000001 EDX: 00000000 ESI: c0131000 EDI: f89dd0a0 EBP: c5213e9c ESP: c5213e78 DS: 007b ES: 007b FS: 00d8 GS: 0033 SS: 0068 CR0: 80050033 CR2: b75878c0 CR3: 1a36a700 CR4: 000406f0 Stack: c4529ea0 c4529ef4 c5213e8c c176d45c c4529ef4 00000000 c4529ea0 c4529fac f89dd0a0 c5213eb0 c1204a68 c5213ed8 c452a2b4 c6680930 c5213ec0 c1204b64 c6680d44 c6680620 c5213eec c120588d ee84b000 ee84b5c0 c5214000 ee84b5e0 Call Trace: [<c176d45c>] ? _raw_spin_unlock+0x2c/0x50 [<c1204a68>] evict+0xa8/0x170 [<c1204b64>] dispose_list+0x34/0x50 [<c120588d>] evict_inodes+0x10d/0x130 [<c11ea941>] generic_shutdown_super+0x41/0xe0 [<c1185190>] ? unregister_shrinker+0x40/0x50 [<c1185190>] ? unregister_shrinker+0x40/0x50 [<c11eac52>] kill_block_super+0x22/0x70 [<f89af23e>] kill_f2fs_super+0x1e/0x20 [f2fs] [<c11eae1d>] deactivate_locked_super+0x3d/0x70 [<c11eb383>] deactivate_super+0x43/0x60 [<c1208ec9>] cleanup_mnt+0x39/0x80 [<c1208f50>] __cleanup_mnt+0x10/0x20 [<c107d091>] task_work_run+0x71/0x90 [<c105725a>] exit_to_usermode_loop+0x72/0x9e [<c1001c7c>] do_fast_syscall_32+0x19c/0x1c0 [<c176dd48>] sysenter_past_esp+0x45/0x74 EIP: [<f89aacb5>] f2fs_evict_inode+0x85/0x490 [f2fs] SS:ESP 0068:c5213e78 ---[ end trace d30536330b7fdc58 ]--- Signed-off-by: Chao Yu <yuchao0@huawei.com> Signed-off-by: Jaegeuk Kim <jaegeuk@kernel.org>		2016-05-20 14:55:41 -07:00
