[SRU][Bionic][linux/linux-gcp][PATCH 0/1] Fix xfs build error

[Kleber Sacilotto de Souza]

This issue has real impact only on linux-gcp, which is the only kernel
that enables CONFIG_XFS_ONLINE_SCRUB. So I'm proposing the fix for
bionic/linux-gcp to be applied to the current cycle, and for
bionic/linux to fix it on the main kernel on a following cycle.
The patch applied for gcp will be gone away on the next rebase.

SRU Justification:

Impact:
The backport of a78ee256c325 ("xfs: convert XFS_AGFL_SIZE to a helper function")
done as part of "Bionic update: upstream stable patchset 2018-08-24"
(bug 1788897) is incomplete, causing the build to fail if
CONFIG_XFS_ONLINE_SCRUB is selected.

/tmp/kernel-kleber-79aa9f7-Y9dG/build/fs/xfs/scrub/agheader.c: In function 'xfs_scrub_walk_agfl':
/tmp/kernel-kleber-79aa9f7-Y9dG/build/fs/xfs/scrub/agheader.c:96:24: error: implicit declaration of function 'XFS_AGFL_SIZE'; did you mean 'XFS_ACL_SIZE'? [-Werror=implicit-function-declaration]
  for (i = flfirst; i < XFS_AGFL_SIZE(mp); i++) {
                        ^~~~~~~~~~~~~
                        XFS_ACL_SIZE

The backport didn't replace all the occurrences of the XFS_AGFL_SIZE macro
by the xfs_agfl_size function.

Fix:
A SAUCE patch is needed to fix the backport, given that the problem doesn't
exist with mainline.

Testcase:
Enable CONFIG_XFS_ONLINE_SCRUB and compile the kernel.
