https://bugzilla.kernel.org/show_bug.cgi?id=216050

Somehow we're getting a page which has a different mapping.

f2fs: set FMODE_CAN_ODIRECT instead of a dummy direct_IO method

2023-06-26T13:07:09+00:00

Since commit a2ad63daa88b ("VFS: add FMODE_CAN_ODIRECT file flag") file
systems can just set the FMODE_CAN_ODIRECT flag at open time instead of
wiring up a dummy direct_IO method to indicate support for direct I/O.

Do that for f2fs so that noop_direct_IO can eventually be removed.

f2fs: fix potential deadlock due to unpaired node_write lock use

2023-06-12T20:04:07+00:00

If S_NOQUOTA is cleared from inode during data page writeback of quota
file, it may miss to unlock node_write lock, result in potential
deadlock, fix to use the lock in paired.

Kworker					Thread
- writepage
 if (IS_NOQUOTA())
   f2fs_down_read(&sbi->node_write);
					- vfs_cleanup_quota_inode
					 - inode->i_flags &= ~S_NOQUOTA;
 if (IS_NOQUOTA())
   f2fs_up_read(&sbi->node_write);

f2fs: support errors=remount-ro|continue|panic mountoption

2023-05-08T18:18:04+00:00

This patch supports errors=remount-ro|continue|panic mount option
for f2fs.

f2fs behaves as below in three different modes:
mode			continue	remount-ro	panic
access ops		normal		noraml		N/A
syscall errors		-EIO		-EROFS		N/A
mount option		rw		ro		N/A
pending dir write	keep		keep		N/A
pending non-dir write	drop		keep		N/A
pending node write	drop		keep		N/A
pending meta write	keep		keep		N/A

By default it uses "continue" mode.
