Hello stable kernel maintainers,
Please backport patch 327ea4adcfa3 ("blkdev_report_zones_ioctl():
Use vmalloc() to allocate large buffers") to at least the v4.17.x and
v4.14.y stable kernel series. That patch fixes a bug introduced in
kernel v4.10. The entire patch is shown below.
Thanks,
Bart.

blkdev_report_zones_ioctl(): Use vmalloc() to allocate large buffers
Avoid that complaints similar to the following appear in the kernel log
if the number of zones is sufficiently large:
fio: page allocation failure: order:9, mode:0x140c0c0(GFP_KERNEL|__GFP_COMP|__GFP_ZERO), nodemask=(null)

Hi,
On the latest 4.9 stable active-passive bonding does not always
failover to the passive slave when carrier is lost on the active
slave. It seems that the issue stems from the backport of
c4adfc822bf5d8e97660b6114b5a8892530ce8cb, bonding: make speed, duplex
setting consistent with link state. There were subsequent patches
which resolved issues with the change to bond_update_speed_duplex
which were not backported. The three commits which seem to resolve the
issue are b5bf0f5b16b9c316c34df9f31d4be8729eb86845,
3f3c278c94dd994fe0d9f21679ae19b9c0a55292 and
ad729bc9acfb7c47112964b4877ef5404578ed13. There are other commits in
mainline which also revolve around
c4adfc822bf5d8e97660b6114b5a8892530ce8cb but are not necessary to
resolving the active-passive failover problems.
Would it be possible to queue up the three commits for backporting to
4.9 stable:
b5bf0f5b16b9c316c34df9f31d4be8729eb86845 bonding: correctly update
link status during mii-commit
3f3c278c94dd994fe0d9f21679ae19b9c0a55292 bonding: fix active-backup transition
ad729bc9acfb7c47112964b4877ef5404578ed13 bonding: require speed/duplex
only for 802.3ad, alb and tlb
All of those commits apply cleanly to 4.9.107.
Thanks,
-nate
