[PATCH] md: yet another attempt to get bitmap-based resync to do the right thing in all cases...
Firstly, R1BIO_Degraded was being set in a number of places in the resync
code, but is never used there, so get rid of those settings.
Then: When doing a resync, we want to clear the bit in the bitmap iff the
array will be non-degraded when the sync has completed. However the current
code would clear the bitmap if the array was non-degraded when the resync
*started*, which obviously isn't right (it is for 'resync' but not for
'recovery' - i.e. rebuilding a failed drive).
This patch calculated 'still_degraded' and uses the to tell bitmap_start_sync
whether this sync should clear the corresponding bit.
