- The oops in git-net.patch has been fixed, so that tree has been restored.
It is huge.
- Added the device-mapper development tree to the -mm lineup (Alasdair
Kergon). It is a quilt tree, living at
ftp://ftp.kernel.org/pub/linux/kernel/people/agk/patches/2.6/editing/.
- Added davidel's signalfd stuff.
Looks like some damage, or maybe intolerance to on-disk damage, to RAID-1.
md1 is the first array on the disk, and it refuses to start up on boot, or after
boot.

The last known version that worked was 2.6.21-rc3-mm1 - I haven't been testing
out the -mm releases so much lately.
Also, Andrew, can you please restart posting/cc'ing your -mm announcements to
the linux-kernel-announce@xxxxxxxxxxxxxxx list? Seems this stopped around about
2.6.20, it was handy.
.config is up at http://www.reub.net/files/kernel/configs/2.6.21-rc5-mm4
Thanks,
Reuben
