PolyServe Kernel Patches

The PolyServe Matrix Server 3.1.2 distribution contains a Linux kernel

patch that can be applied at the customer’s discretion. This problem has

been reported to SuSE.

The following patch is provided for all supported kernels:

• 00_imapping_race.patch. This patch adds a reference to a filesystem

inode when it is acquired to prevent a race condition that can occur

when the i_mapping pointer is performing sync operations. Without

this patch, the kernel will panic if the race occurs.

The patches are included in the PolyServe Support RPM.

Deinstall Patches

The Support RPM automatically installs the kernel patch. If you do not

want to run with the patch, you can deinstall it after you have installed

the PolyServe Support RPM.

To deinstall a patch, run these commands:

# cd /usr/src/linux

# patch -R -p1 < /usr/src/polyserve/<kernel>/patches/patch_filename
