Neil,
Are these patches safe to apply against 2.4 kernels?
It looks like one or more of these might reduce the chances of the
kernel oops I experience on occasion when manipulating arrays.
Also, this appears to change some of the way rebuilds are done, and am
interested to see if this impacts some of the rebuild performance issues
I've been seeing.
Thanks!
Sean.
