commit bc37e4fb5cac2925b2e286b1f1d4fc2b519f7d92 upstream.
This reverts commit 4b8628d57b725b32616965e66975fcdebe008fe7.
XFS quota has had the concept of a "quota warning limit" since the earliest Irix implementation, but a mechanism for incrementing the warning counter was never implemented, as documented in the xfs_quota(8) man page. We do know from the historical archive that it was never incremented at runtime during quota reservation operations.
With this commit, the warning counter quickly increments for every allocation attempt after the user has crossed a quote soft limit threshold, and this in turn transitions the user to hard quota failures, rendering soft quota thresholds and timers useless. This was reported as a regression by users.
Because the intended behavior of this warning counter has never been understood or documented, and the result of this change is a regression in soft quota functionality, revert this commit to make soft quota limits and timers operable again.
