Date: Fri May 21 2010 - 18:48:14 EST
Hi Linus,
please pull the following updates for md for 2.6.35.
The head commit is a merge which fixes up a conflict between some
patches in here and other that went in late in 2.6.34,
and also resolves a compile-time conflict with sysfs patches (which
added an arg to sysfs_get_dirent (as discovered in -next).
All have been seen on linux-raid mailing list and have been in -next
for a while.
The first few are tagged for -stable.
Thanks,
NeilBrown
