[PATCH 1/2] md bitmap bug fixes

Neil,

here are a couple of patches -- this one for the kernel, the next for mdadm. They fix a few issues that I found while testing the new bitmap intent logging code.

Briefly, the issues were:

kernel:

added call to bitmap_daemon_work() from raid1d so that the bitmap would actually get cleared

fixed the marking of pages with BITMAP_CLEAN so that the bitmap would get cleared correctly after resync and normal write I/O

pass back errors from write_page() since it now does actual writes itself

sync_size changed to sectors (was array_size which was KB) -- some divisions by 2 were needed

mdadm:

avoid setting of sb->events_lo = 1 when creating a 0.90 superblock -- it doesn't seem to be necessary and it was causing the event counters to start at 4 billion+ (events_lo is actually the high part of the events counter, on little endian machines anyway)

some sync_size changes, as in the kernel

if'ed out super1 definition which is now in the kernel headers

included sys/time.h to avoid compile error


Thanks,
Paul
