Jeff, I shall send all the sata patches which I have at you one single time
and I shall then drop the lot. So please don't flub them.
I'll then do a rc1-mm2 without them.
hm, this is looking like a lot of work for not much gain. Rafael, are
you able to do a quick chop and tell us whether these:
The md one and the long history of reports about parallel I/O causing
problems sounds a lot more like the kmap stuff you were worried about
Andrew. I'd be very intereste dto know if it happens on x86_32 built with
a standard memory split and no highmem....
2.6.20-rc1 works, and 2.6.20-rc1 does not have the kmap_atomic() fix.
Upstream does kmap_atomic(KM_USER0) and -mm does kmap_atomic(KM_IRQ0)
