[PATCH] md - 0 of 10 - Intro

Hi.
 Following are 10 patches for md in 2.6.1-lastest.
 
 1-6 are simple bugfixes that I am confident should be in 2.6.2.

 7 is a bugfix that is fairly important, but could probably do with a
 bit more testing first.  It is not impossible that it could deadlock,
 though I think I have caught and fixed all the problems.

 8-10 are code simplication.

 So maybe 7-10 should only go in -mm for now, but if it is a while
 before 2.6.2, then maybe they can go in a 2.6.2-pre.

Thanks,
NeilBrown
