Bug Description
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_
/tmp/kernel-
/tmp/kernel-
for (i = flfirst; i < XFS_AGFL_SIZE(mp); i++) {
The backport didn't replace all the occurrences of the XFS_AGFL_SIZE 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_
Note: bionic/linux doesn't have this config option enabled. The only 4.15 kernel with this config is bionic/linux-gcp, so it affects only this kernel and its backport.
