I did not change the flush related code until the last patches. I added REQ_OP_FLUSH in patch: [PATCH 33/35] block, drivers: add REQ_OP_FLUSH operation commit 18dea20363ba245a47bc1bb54f6465b8a05b19af Author: Mike Christie <mchristi@xxxxxxxxxx> Date: Tue Jan 5 21:02:17 2016 -0600 block, drivers: add REQ_OP_FLUSH operation and I added the REQ_PREFLUSH flag in [PATCH 35/35] block, drivers, fs: rename REQ_FLUSH to REQ_PREFLUSH commit 303dc6a7cc3673065538ba041562fcd833a619af Author: Mike Christie <mchristi@xxxxxxxxxx> Date: Thu Jan 7 18:17:03 2016 -0600 block, drivers, fs: rename REQ_FLUSH to REQ_PREFLUSH I did them in separate patches, because I was not sure if they were correct with what you requested before, and because they were a little more tricky because of how request_fn drivers, make_request_fn drivers, and dm-multipath handle flushes differently. _______________________________________________ xfs mailing list xfs@xxxxxxxxxxx http://oss.sgi.com/mailman/listinfo/xfs
