Hi,
As the first bit of the DBRD patch already got upstream (see commit 10fc89d01a) it is time to get more of DRBD towards mainline.
Please consider the lru_cache as next building block of DRBD for inclusion.
Patch set attached. Git tree available: git pull git://git.drbd.org/linux-2.6-drbd.git drbd
We are looking for reviews!
Note for reviewers:
Only the first patch (lru_cache) is self contained. The other patches are just split at file boundaries. Sorry, DRBD was developed as out-of-tree modules just for too long.
Short Description
DRBD is a shared-nothing, synchronously replicated block device. It is designed to serve as a building block for high availability clusters and
in this context, is a "drop-in" replacement for shared storage. Simplistically, you could see it as a network RAID 1.

Changes since 2009-05-15
* Cleanup: Moved lru_cache.c to /lib * Cleanup: all STATIC -> static * Cleanup: Removed drbd_config.h ; New Kconfig option: CONFIG_DRBD_FAULT_INJECTION * Cleanup: Removed drbd_buildtag.c * DRBD: Following DRBD-upstream, now at 8.3.2-rc2. Relevant changes: * DRBD: lru_cache: use pointer arrays and kmem_cache * DRBD: Fixed for building on big endian architectures * DRBD: Fixed nl stuff to work on architectures that does not do unaligned memory accesses * DRBD: Deal with hash functions already ported to SHASH * DRBD: GFP_KERNEL -> GFP_NOIO in various places
Changes since 2009-04-30
* Cleanup: Removed typecasts, more documentation in lru_cache. Moved to /lib * Cleanup: replaced __attribute__((packed)) with __packed * Cleanup: remove quite a few 'inline's from .c files * Cleanup: renaming a few constants: _SECT -> _SECTOR_SIZE, _SIZE_B -> _SHIFT ... * Cleanup: rename inc_local -> get_ldev; inc_net -> get_net_conf; and corresponding dec_* -> put_* * Cleanup: rename mdev->bc to mdev->ldev (to match the recent change to get_ldev/put_ldev) * Cleanup: Made function comments kernel-doc compliant * Cleanup: vmalloc() only as a fall back for kmalloc() * DRBD: Allow detach of a SyncTarget node. (Bugz 221) * DRBD: Call drbd_rs_cancel_all() and reset rs_pending when aborting resync due to detach. (Bugz 223) * DRBD: make drbd thread t_lock irqsave - lockdep complained, and lockdep is right (theoretically)
Changes since 2009-04-10
* Cleanup: Removed all CamelCase * Cleanup: Replaced DRBD's own tracing stuff with regular tracepoints * Cleanup: Removed ERR/INFO/ALERT ... macros, using dev_err/dev_info/... now * Cleanup: Minor stuff, as suggested in feedback on LKML * DRBD: Bitmap compression feature was finalised * DRBD: new disable_sendpage parameter
Changes since the post on 2009-03-30, all triggered by reviews
* Improvements to Makefile and Kconfig * Simplified definitions of bm_flags' bitnumbers * Removed debugging aid
Changes since the post on 2009-03-23, from drbd-mainline
* Updated to the final drbd-8.3.1 code * Optionally run-length encode bitmap transfers
Changes since the post on 2009-03-23, triggered by reviews
* Using the latest proc_create() now * Moved the allocation of md_io_tmpp to attach/detach out of drbd_md_sync_page_io() * Removing the mode selection comments for emacs * Removed DRBD_ratelimit()
cheers, Phil
