Merge tag 'for_v5.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jack/linux-fs

2019-11-30T19:16:07+00:00

Pull ext2, quota, reiserfs cleanups and fixes from Jan Kara:

 - Refactor the quota on/off kernel internal interfaces (mostly for
   ubifs quota support as ubifs does not want to have inodes holding
   quota information)

 - A few other small quota fixes and cleanups

 - Various small ext2 fixes and cleanups

 - Reiserfs xattr fix and one cleanup

ext2: check err when partial != NULL

2019-11-05T09:42:18+00:00

Check err when partial == NULL is meaningless because
partial == NULL means getting branch successfully without
error.

iomap: use a srcmap for a read-modify-write I/O

2019-10-21T15:51:59+00:00

The srcmap is used to identify where the read is to be performed from.
It is passed to ->iomap_begin, which can fill it in if we need to read
data for partially written blocks from a different location than the
write target.  The srcmap is only supported for buffered writes so far.

[hch: merged two patches, removed the IOMAP_F_COW flag, use iomap as
      srcmap if not set, adjust length down to srcmap end as well]

All but one bail out paths in ext2_iget() is releasing bh. Move the
releasing of bh into a common error handling code.

ext2: Adjust the comment of function ext2_alloc_branch

2019-03-26T10:21:23+00:00

The name of argument is error in the header comment.
@num should be @indirect_blks.
At the same time, there was a lack of description of the two parameters
@blks and @goal.
This commit therefore fixes this header comment.

ext2: support statx syscall

2019-02-18T14:14:43+00:00

Since statx, every filesystem should fill the attributes/attributes_mask
in routine getattr. But the generic_fillattr has not fill that, so add
ext2_getattr to do this. This can fix generic/424 while testing ext2.

ext2: Annotate implicit fall through in __ext2_truncate_blocks

2019-01-28T14:50:45+00:00

There is a plan to build the kernel with -Wimplicit-fallthrough and
these places in the code produced warnings (W=1).

This commit removes the following warnings:

  fs/ext2/inode.c:1237:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
  fs/ext2/inode.c:1244:7: warning: this statement may fall through [-Wimplicit-fallthrough=]
