tristate "GFS2 file system support"
block: rename CONFIG_LBD to CONFIG_LBDAF Follow-up to "block: enable by default support for large devices and files on 32-bit archs". Rename CONFIG_LBD to CONFIG_LBDAF to: - allow update of existing [def]configs for "default y" change - reflect that it is used also for large files support nowadays Signed-off-by: Bartlomiej Zolnierkiewicz <bzolnier@gmail.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

GFS2: Merge lock_dlm module into GFS2 This is the big patch that I've been working on for some time now. There are many reasons for wanting to make this change such as: o Reducing overhead by eliminating duplicated fields between structures o Simplifcation of the code (reduces the code size by a fair bit) o The locking interface is now the DLM interface itself as proposed some time ago. o Fewer lookups of glocks when processing replies from the DLM o Fewer memory allocations/deallocations for each glock o Scope to do further optimisations in the future (but this patch is more than big enough for now!) Please note that (a) this patch relates to the lock_dlm module and not the DLM itself, that is still a separate module; and (b) that we retain the ability to build GFS2 as a standalone single node filesystem with out requiring the DLM. This patch needs a lot of testing, hence my keeping it I restarted my -git tree after the last merge window. That way, this has the maximum exposure before its merged. This is (modulo a few minor bug fixes) the same patch that I've been posting on and off the the last three months and its passed a number of different tests so far.

GFS2: Umount recovery race fix This patch fixes a race condition where we can receive recovery requests part way through processing a umount. This was causing problems since the recovery thread had already gone away. Looking in more detail at the recovery code, it was really trying to implement a slight variation on a work queue, and that happens to align nicely with the recently introduced slow-work subsystem. As a result I've updated the code to use slow-work, rather than its own home grown variety of work queue. When using the wait_on_bit() function, I noticed that the wait function that was supplied as an argument was appearing in the WCHAN field, so I've updated the function names in order to produce more meaningful output.

Allows a cluster of computers to simultaneously use a block device
that is shared between them (with FC, iSCSI, NBD, etc...). GFS reads
and writes to the block device like a local filesystem, but also uses
a lock module to allow the computers coordinate their I/O so
filesystem consistency is maintained. One of the nifty features of
GFS is perfect consistency -- changes made to the filesystem on one
machine show up immediately on all other machines in the cluster.

[GFS2] No lock_nolock This patch merges the lock_nolock module into GFS2 itself. As well as removing some of the overhead of the module, it also means that its now impossible to build GFS2 without a lock module (which would be a pointless thing to do anyway). We also plan to merge lock_dlm into GFS2 in the future, but that is a more tricky task, and will therefore be a separate patch.

The "nolock" lock module is now built in to GFS2 by default. If
you want to use the DLM, be sure to enable HOTPLUG and IPv4/6
networking.
