md/bitmap: fix calculation of 'chunks' - missing shift.

2012-05-04T07:03:18Z

commit 61a0d80c "md/bitmap: discard CHUNK_BLOCK_SHIFT macro" replaced CHUNK_BLOCK_RATIO() by the same text that was replacing CHUNK_BLOCK_SHIFT() - which is clearly wrong. The result is that 'chunks' is often too small by 1, which can sometimes result in a crash (not sure how). So use the correct replacement, and get rid of CHUNK_BLOCK_RATIO which is no longe used.

md/bitmap: discard CHUNK_BLOCK_SHIFT macro

2012-03-19T01:46:41Z

Be redefining ->chunkshift as the shift from sectors to chunks rather than bytes to chunks, we can just use "bitmap->chunkshift" which is shorter than the macro call, and less indirect. Signed-off-by: NeilBrown

md/bitmap: move printing of bitmap status to bitmap.c

2012-03-19T01:46:40Z

The part of /proc/mdstat which describes the bitmap should really be generated by code in bitmap.c. So move it there. Signed-off-by: NeilBrown

md: remove typedefs: mddev_t -> struct mddev

2011-10-11T05:47:53Z

Having mddev_t and 'struct mddev_s' is ugly and not preferred Signed-off-by: NeilBrown

MD bitmap: Revert DM dirty log hooks

2011-07-27T01:00:37Z

Revert most of commit e384e58549a2e9a83071ad80280c1a9053cfd84c md/bitmap: prepare for storing write-intent-bitmap via dm-dirty-log. MD should not need to use DM's dirty log - we decided to use md's bitmaps instead. Keeping the DIV_ROUND_UP clean-ups that were part of commit e384e58549a2e9a83071ad80280c1a9053cfd84c, however.

md/bitmap: remove unused fields from struct bitmap

2011-06-09T01:43:01Z

Get rid of ->syncchunk and ->counter_bits since they're never used. Also discard COUNTER_BYTE_RATIO which is unused. Signed-off-by: Namhyung Kim Signed-off-by: NeilBrown

md: use sector_t in bitmap_get_counter

2010-10-28T06:32:26Z

bitmap_get_counter returns the number of sectors covered by the counter in a pass-by-reference variable. In some cases this can be very large, so make it a sector_t for safety. Signed-off-by: NeilBrown

md/bitmap: separate out loading a bitmap from initialising the structures.

2010-07-26T03:21:34Z

dm makes this distinction between ->ctr and ->resume, so we need to too. Also get the new bitmap_load to clear out the bitmap first, as this is most consistent with the dm suspend/resume approach Signed-off-by: NeilBrown
