Hello Jaegeuk Kim,
The patch 17ef549eef6e: "f2fs: use meta_inode cache to improve
roll-forward speed" from Sep 11, 2014, leads to the following static
checker warning:
fs/f2fs/recovery.c:180 find_fsync_dnodes()
warn: 'page' isn't an ERR_PTR
fs/f2fs/recovery.c

In ->get_victim we get max_search value from dirty_i->nr_dirty without
protection of seglist_lock, after that, nr_dirty can be increased/decreased
before we hold seglist_lock lock.
Then in main loop we attempt to traverse all dirty section one time to find
victim section, but it's not accurate to u
In manual of mount, we descript remount as below:
"mount -o remount,rw /dev/foo /dir
After this call all old mount options are replaced and arbitrary stuff from
fstab is ignored, except the loop= option which is internally generated and
maintained by the mount command."
Previously f2fs do not cl
Now punching hole in directory is not supported in f2fs, so let's limit file
type in punch_hole().
In addition, in punch_hole if offset is exceed file size, we should skip
punching hole.

By using FALLOC_FL_KEEP_SIZE in ->fallocate of f2fs, we can fallocate block past
EOF without changing i_size of inode. These blocks past EOF will not be
truncated in ->setattr as we truncate them only when change the file size.
We should give a chance to truncate blocks out of filesize in setattr(
Block size in f2fs is 4096 bytes, so theoretically, f2fs can support 4096 bytes
sector device at maximum. But now f2fs only support 512 bytes size sector, so
block device such as zRAM which uses page cache as its block storage space will
not be mounted successfully as mismatch between sector size o
