*	dm raid1: keep retrying alloc if mempool_alloc failed	Mikulas Patocka	2009-06-22	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \| \|	If the code can't handle allocation failures, use __GFP_NOFAIL so that in case of memory pressure the allocator will retry indefinitely and won't return NULL which would cause a crash in the function. This is still not a correct fix, it may cause a classic deadlock when memory manager waits for I/O being done and I/O waits for some free memory. I/O code shouldn't allocate any memory. But in this case it probably doesn't matter much in practice, people usually do not swap on RAID.

*	dm raid1: separate region_hash interface part1	Heinz Mauelshagen	2008-10-21	1	-0/+704
	Separate the region hash code from raid1 so it can be shared by forthcoming targets. Use BUG_ON() for failed async dm_io() calls. Signed-off-by: Heinz Mauelshagen <hjm@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
