Squashfs: add additional inode sanity checking
[ Upstream commit 9ee94bfbe930a1b39df53fa2d7b31141b780eb5a ]
Patch series "Squashfs: performance improvement and a sanity check".
This patchset adds an additional sanity check when reading regular file
inodes, and adds support for SEEK_DATA/SEEK_HOLE lseek() whence values.
This patch (of 2):
Add an additional sanity check when reading regular file inodes.
A regular file if the file size is an exact multiple of the filesystem
block size cannot have a fragment. This is because by definition a
fragment block stores tailends which are not a whole block in size.
