[PATCH md 000 of 14] Introduction

[NeilBrown <neilb@suse.de>]

Following are 14 more patches for md in 2.6.15-rc2-mm1

None are appropriate for 2.6.15 - all should wait for 2.6.16 to open.

With these the handling for read errors by overwriting with correct
data is supported for all relevant raid levels.  Also user-requested
checking of redundant information is supported for all levels, and
report the number of affect blocks in sysfs (though this number is
only approximate).

/proc/mdstat becomes pollable so that mdadm can get timely
notification of changes without polling at a high frequency.

There are also a substantial number of code cleanups.
