Results from Linaro's test farm.
Regressions on x86_64, and i386.

Reported-by: Linux Kernel Functional Testing <lkft@linaro.org>

Following kernel warnings have been noticed on  x86_64, qemu-x86_64 and
qemu-i386 while running LTP cve ioctl_sg01 tests the kernel with stable-rc
6.6.26-rc1 and 6.8.5-rc1.

Reverted this patch and I couldn't see the repoted warning.

[ Upstream commit 27f58c04a8f438078583041468ec60597841284d ]

This has been reported on stable-rc 6.8.3-rc1 [1].
