Hello,
after this commit I'm experiencing some filesystem corruptions at boot
on a power9 box with an aacraid controller.
At the moment I'm running a 5.15.30 kernel; when the filesystem is
mounted at boot I see the following errors in the console:
Begin: Will now check root file system ... fsck from util-linux 2.36.1

[ 4.747771] EXT4-fs (sda2): mounted filesystem with ordered data mode. Opts: (null). Quota mode: none.
If I reboot multiple times fsck requires a manual fix and I get dropped
to the initramfs shell. Some times the filesystem gets corrupted and I
need to redeploy the box.
If I use the same kernel with this commit reverted I can reboot as many
times as I want without any failure:
813c6871f76b ("scsi: core: Reallocate device's budget map on queue depth change")
I would not have thought that this causes possible corruption.
For now I've just reverted the commit, but I'll try to add some
debugging and collect more info.
Let me know if there's any specific test that you want me to try.
Please try this:
https://lore.kernel.org/linux-scsi/yq1ee2kumrh.fsf@xxxxxxxxxxxxxxxxxxxx/T/#t
It never made 5.17, which I would have hoped for.
Thanks,
John
