Subject: [GIT PULL] vfs: fixes for 5.18-rc1

Hi Linus,

Please pull this branch of VFS bugfixes for 5.18-rc1.  The erofs
developers felt that FIEMAP should handle ranged requests starting at
s_maxbytes by returning EFBIG instead of passing the filesystem
implementation a nonsense 0-byte request.

Not sure why they keep tagging this 'iomap', but the VFS shouldn't be
asking for information about ranges of a file that the filesystem
already declared that it does not support.

As usual, I did a test-merge with upstream master as of a few minutes
ago, and didn't see any conflicts.  Please let me know if you encounter
any problems.
