GFS2: use depends instead of select in kconfig

2012-03-26T08:18:02+00:00

Avoids having to duplicate the dependencies of what is 'select'ed (and on
down...)

Those dependencies are currently incomplete, leading to broken builds with
GFS2_FS_LOCKING_DLM=y and IP_SCTP=n.

from GFS2.

gfs2: use workqueue instead of slow-work

2010-07-23T11:14:25+00:00

Workqueue can now handle high concurrency.  Convert gfs to use
workqueue instead of slow-work.

* Steven pointed out that recovery path might be run from allocation
  path and thus requires forward progress guarantee without memory
  allocation.  Create and use gfs_recovery_wq with rescuer.  Please
  note that forward progress wasn't guaranteed with slow-work.

* Updated to use non-reentrant workqueue.

GFS2: do not select QUOTA

2010-03-09T10:08:36+00:00

gfs2 only needs the quotactl code, not the generic quota implementation.

Revert "task_struct: make journal_info conditional"

2009-12-17T21:23:24+00:00

This reverts commit e4c570c4cb7a95dbfafa3d016d2739bf3fdfe319, as
requested by Alexey:

 "I think I gave a good enough arguments to not merge it.
  To iterate:
   * patch makes impossible to start using ext3 on EXT3_FS=n kernels
     without reboot.
   * this is done only for one pointer on task_struct"

  None of config options which define task_struct are tristate directly
  or effectively."

task_struct: make journal_info conditional

2009-12-15T16:53:27+00:00

journal_info in task_struct is used in journaling file system only.  So
introduce CONFIG_FS_JOURNAL_INFO and make it conditional.

GFS2: Hook gfs2_quota_sync into VFS via gfs2_quotactl_ops

2009-12-03T11:49:09+00:00

The plan is to add further operations to the gfs2_quotactl_ops
in future patches. The sync operation is easy, so we start with
that one.

We plan to use the XFS quota control functions because they more
closely match the GFS2 ones.

block: rename CONFIG_LBD to CONFIG_LBDAF

2009-06-19T06:08:50+00:00

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

GFS2: Umount recovery race fix

2009-05-19T09:01:18+00:00

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.

GFS2: Merge lock_dlm module into GFS2

2009-03-24T11:21:14+00:00

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.
