Subject: [PULL REQUEST] md updates for 2.6.35


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
