-Subject: ntp: Fixup adjtimex freq validation on 32-bit systems
-
-Additional validation of adjtimex freq values to avoid
-potential multiplication overflows were added in commit
-5e5aeb4367b (time: adjtimex: Validate the ADJ_FREQUENCY values)
-
-Unfortunately the patch used LONG_MAX/MIN instead of
-LLONG_MAX/MIN, which was fine on 64-bit systems, but being
-much smaller on 32-bit systems caused false positives
-resulting in most direct frequency adjustments to fail w/
-EINVAL.
-
-ntpd only does direct frequency adjustments at startup, so
-the issue was not as easily observed there, but other time
-sync applications like ptpd and chrony were more effected by
-the bug.
-
-See bugs:
-
- https://bugzilla.kernel.org/show_bug.cgi?id=92481
- https://bugzilla.redhat.com/show_bug.cgi?id=1188074
-
-This patch changes the checks to use LLONG_MAX for
-clarity, and additionally the checks are disabled
-on 32-bit systems since LLONG_MAX/PPM_SCALE is always
-larger then the 32-bit long freq value, so multiplication
-overflows aren't possible there.

+Basically this is a copy of commit 001e4a8775f6(ext4: implement cgroup
+writeback support). Tested with a fio test, verified writeback is
+throttled against cgroup io.max write bandwidth, also verified moving
+the fio test to another cgroup and the writeback is throttled against
+new cgroup setting.
