== Fix ==
* e093c4be (xfs: Fix tail rounding in xfs_alloc_file_space())
This patch can be cherry-picked in D/E and needs some minor context
adjustmest on X/B.
== Test ==
Test kernels can be found here:
https://people.canonical.com/~phlin/kernel/lp-1865967-xfs-fallocate06/
All patched kernels are working as expected, this issue will no longer
exist on XFS:

== Regression Potential ==
Low, this ensures all the blocks are properly allocated and it's only
affecting the allocation on XFS.

test issue addressed in bug 1866323.
