The following changes since commit 504c6d1b44bc6e694bdba8d9a2a4e046275b5e2b:
Vivek Goyal (1):
amiga floppy: Compile failure fixes
are available in the git repository at:
http://git.drbd.org/linux-2.6-drbd.git for-jens
Dan Carpenter (1):
drbd: cleanup: change "<= 0" to "== 0"
Lars Ellenberg (33):
drbd: fix list corruption (recent regression)
drbd: let drbd_free_ee implicitly free any digest
drbd: remove outdated comment and dead code
drbd: use rolling marks for resync speed calculation
drbd: reduce code duplication when receiving data requests
drbd: new configuration parameter c-min-rate
drbd: fix race between deconfiguring and reconfiguring network
drbd: fix race on meta-data update
drbd: implicitly create unconfigured devices on sync-after dependencies
drbd: fix race on meta-data update, addendum
drbd: drbd_md_sync before calling user space helpers
drbd: don't count sendpage()d pages only referenced by tcp as in use
drbd: fix potential kernel BUG (NULL deref)
drbd: fix spurious protocol error
drbd: cosmetic, don't report resync for online-verify
drbd: fix for spurious full sync (becoming sync target looked like invalidate)
drbd: DIV_ROUND_UP not needed here
drbd: protocol compatibility for maximum packet sizes
drbd: fix possible access after free
drbd: Fix regression in recv_bm_rle_bits (compressed bitmap)
drbd: drbd_send_ack_dp must not rely on header information
drbd: preparation commit, using full state in receive_state()
drbd: allow for explicit resync-finished notifications
drbd: fix for spurious fullsync (uuids rotated too fast)
drbd: fix unlikely access after free and list corruption
drbd: fix for possible deadlock on IO error during resync
drbd: add explicit drbd_md_sync to drbd_resync_finished
drbd: cleanup useless leftover warn/error printk's
drbd: drop wrong debug asserts, fix recently introduced race
drbd: add some more explicit drbd_md_sync
drbd: relax the grace period of the md_sync timer again
drbd: use dynamic_dev_dbg to optionally log uuid changes
drbd: add race-breaker to drbd_go_diskless
Philipp Reisner (42):
drbd: renamed drbd_tl_epoch.n_req to drbd_tl_epoch.n_writes
drbd: Track all IO requests on the TL, not writes only
drbd: mod_req has now a return value
drbd: factored tl_restart() out of tl_clear().
drbd: Do not send two barriers without any writes between them
drbd: factored drbd_req_make_private_bio() out of drbd_req_new()
drbd: Removed redundant error checks in the request code path
drbd: Finished the "on-no-data-accessible suspend-io;" functionality
drbd: Do not allow a fencing-policy of resource-and-stonith with protocol A
drbd: Disabled the crashed_primary detection for re-attach of last data while IO is frozen
drbd: Now we need to handle the ed_uuid of an diskless, unconnected primary correctly
drbd: Removing a by now obsolete clause in the state sanitizing
drbd: Reduce the verbosity of some state transitions
drbd: Run the fence-peer helper asynchronously
drbd: Delayed creation of current-UUID
drbd: Ensure that the peer was not rebootet in the meantime before resending TL
drbd: Do not do a hard state change when establishing a connection [bugz 304]
drbd: Fixed a deadlock, probably only affected UP machines
drbd: Allow tl_restart() to do IO completion while IO is suspended
drbd: Allow attach while IO is suspended
drbd: Do not try to free tl_hash in drbd_disconnect() when IO is suspended
drbd: Make sure tl_restart(, resend) can not get called multiple times for a new connection
drbd: Initialize all members of sync_conf to their defaults [Bugz 315]
drbd: New sync parameters for the smart resync rate controller
drbd: New sync_param packet, that includes the parameters of the new controller
drbd: The new, smarter resync speed controller
drbd: Bugfix: rs_in_flight could become wrong if read_for_csum() requested reschedule later
drbd: Replaced some casts by an union. Improved comments
drbd: Microfix: Assigning sector once is sufficient
drbd: Bugfix for regression introduced with f9bc8913c06022e
drbd: Sending of big packets, for payloads from 64KByte to 4GByte
drbd: receiving of big packets, for payloads between 64kByte and 4GByte
drbd: Actually allow BIOs up to 128k (was 32k).
drbd: Disable activity log updates when the whole device is out of sync
drbd: Removed a race that could cause unexpected execution of w_make_resync_request()
drbd: Adding support for BIO/Request flags: REQ_FUA, REQ_FLUSH and REQ_DISCARD
drbd: Fixed compatibility with protocol versions smaller than 95
drbd: Track the reasons to suspend IO in dedicated state bits
drbd: Allow larger values for c-fill-target.
drbd: Fixed a stupid copy and paste error
drbd: Do not log an ASSERT for P_OV_REQUEST packets while C_CONNECTED
dynamic_debug.h: Fix dynamic_dev_dbg() macro if CONFIG_DYNAMIC_DEBUG not set
