[dm-devel] [PATCH 0/1] patches to improve cluster raid1 performance [V3]



use DM_INTEGRATED_FLUSH to indicate the new option of flush request.
when using DM_INTEGRATED_FLUSH, the payload of flush request is the 
same as mark region request.

'X' means we have this kind of request, while '0' means none.

mark request :     X               X               0

clear request:     X               0               X

flush method:    payload_flush   payload_flush   delayed flush
