Hi everybody,
I just tried to patch a Linux 2.2.14 kernel to make use of the current
software raid. Someone did a minor change to drivers/block/raid0.c
from 2.2.13 to 2.2.14, so one hunk of raid0145-19990824 failed (diff
output below).
I think this should be introduced into the current raid patch.
pipc22:/usr/src/linux-2.2.13/drivers/block> diff -u raid0.c
