[PATCH v2 0/1] fallocate missing fd_offset

[“William Roche]

From: William Roche <william.roche@oracle.com>

Working on the poisoned memory recovery mechanisms with David
Hildenbrand, it appeared that the file hole punching done with
the memory discard functions are missing the file offset value
fd_offset to correctly modify the right file location.

Note that guest_memfd would not currently take into account
fd_offset, so I'm adding a comment next to the fallocate use
in ram_block_discard_guest_memfd_range().

This version is also checkpatch.pl clean
make check runs fine on both ARM and x86

v1->v2
  . replacing the ram_block_discard_guest_memfd_range()
    modifications with a comment
  . use a local variable for the global file offset
