Subject: [PATCH 00/23] RFC DRBD fixes
Date: Thu, 3 Jul 2014 10:42:52 +0200 [thread overview]
Message-ID: <1404376995-4877-1-git-send-email-philipp.reisner@linbit.com> (raw)
Hi,
this series adds a debugfs hierarchy to DRBD. It unveils a lot
of information about timing of states/stages of IO requests.
This information helps a lot while optimizing DRBD for SSD
based IO stacks.
Dan Carpenter (1):
drbd: silence underflow warning in read_in_block()
Lars Ellenberg (22):
drbd: poison free'd device, resource and connection structs
drbd: fix drbd_destroy_device reference count updates
drbd: track meta data IO intent, start and submit time
drbd: gather detailed timing statistics for drbd_requests
drbd: add lists to find oldest pending requests
drbd: add caching oldest request pointers for replication stages
drbd: improve throttling decisions of background resynchronisation
drbd: track timing details of peer_requests
drbd: register peer requests on read_ee early
drbd: track details of bitmap IO
drbd: debugfs: add basic hierarchy
drbd: debugfs: add in_flight_summary data
drbd: debugfs: deal with destructor racing with open of debugfs file
drbd: debugfs: Add in_flight_summary
drbd: debugfs: add callback_history
drbd: debugfs: add per volume oldest_requests
drbd: debugfs: add version tag to debugfs files
drbd: debugfs: add per connection oldest requests
drbd: debugfs: add per device data_gen_id
drbd: resync should only lock out specific ranges
drbd: drop spurious parameters from _drbd_md_sync_page_io
drbd: implicitly truncate cpu-mask
