Merge tag 'vfs-5.18-merge-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux
Pull vfs fix from Darrick Wong: "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. - Fix a potential infinite loop in FIEMAP by fixing an off by one error when comparing the requested range against s_maxbytes" * tag 'vfs-5.18-merge-1' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux: fs: fix an infinite loop in iomap_fiemap
