Fixes: ceph#13220 Backport: hammer Signed-off-by: Jason Dillaman <dillaman@redhat.com> (cherry picked from commit a1e99f0)
Added support for read2, write2, aio_read2, and aio_write2 APIs. Fixes: 13325 Backport: hammer Signed-off-by: Jason Dillaman <dillaman@redhat.com> (cherry picked from commit b5b4a9d)
Fixes: ceph#13221 Backport: hammer Signed-off-by: Jason Dillaman <dillaman@redhat.com> (cherry picked from commit 4f436e1)
Only track read-after-write and write-after-write IO dependencies via the associated write completions. All IO events after a write completion are considered to be dependent and can be pruned down to at most the number of concurrent IOs. This reduces the prep time from a simple 'rbd bench-write' from over 4 hrs down to seconds. Fixes: ceph#13378, ceph#13384 Backport: hammer Signed-off-by: Jason Dillaman <dillaman@redhat.com> (cherry picked from commit 65fb1b8)
Avoid building the entire prep event history in memory before attempting to write the prepped trace file. Signed-off-by: Jason Dillaman <dillaman@redhat.com> (cherry picked from commit 98f513a)
This new command-line will dump all the processed events as they are extracted from the trace file. Signed-off-by: Jason Dillaman <dillaman@redhat.com> (cherry picked from commit 646e50a)

this must be merged together with #6580 to not cause packaging problems. Good to merge otherwise: It went through a rbd suite ( http://tracker.ceph.com/issues/13356#note-24 ) with one failure that could not be repeated ( http://tracker.ceph.com/issues/13804 ). |
