Lars Ellenberg e3881a6816 [PATCH] md: pass down BIO_RW_SYNC in raid{1,10} ... md raidX make_request functions strip off the BIO_RW_SYNC flag, thus introducing additional latency. Fixing this in raid1 and raid10 seems to be straightforward enough. For our particular usage case in DRBD, passing this flag improved some initialization time from ~5 minutes to ~5 seconds.
