* DLM must depend on SYSFSAdrian Bunk2007-07-071-1/+1
| | | | | | | | | | | | | | | | | | | | | The dependency of DLM on SYSFS got lost in commit 6ed7257b46709e87d79ac2b6b819b7e0c9184998 resulting in the following compile error with CONFIG_DLM=y, CONFIG_SYSFS=n: <-- snip --> ... LD .tmp_vmlinux1 fs/built-in.o: In function `dlm_lockspace_init': /home/bunk/linux/kernel-2.6/linux-2.6.22-rc6-mm1/fs/dlm/lockspace.c:231: undefined reference to `kernel_subsys' fs/built-in.o: In function `configfs_init': /home/bunk/linux/kernel-2.6/linux-2.6.22-rc6-mm1/fs/configfs/mount.c:143: undefined reference to `kernel_subsys' make[1]: *** [.tmp_vmlinux1] Error 1 <-- snip --> Signed-off-by: Adrian Bunk <bunk@stusta.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* [DLM] Consolidate transport protocolsPatrick Caulfield2007-05-011-24/+7
| | | | | | | | | | | | | | | This patch consolidates the TCP & SCTP protocols for the DLM into a single file and makes it switchable at run-time (well, at least before the DLM actually starts up!) For RHEL5 this patch requires Neil Horman's patch that expands the in-kernel socket API but that has already been twice ACKed so it should be OK. The patch adds a new lowcomms.c file that replaces the existing lowcomms-sctp.c & lowcomms-tcp.c files.

Yes, patch below. > regards, cu Adrian <-- snip --> This patch fixes a circular dependency by letting GFS2_FS_LOCKING_DLM and DLM depend on instead of select SYSFS. Since SYSFS depends on EMBEDDED this change shouldn't cause any problems for users.

| | | | | | | | | | | | | | | | | With CONFIG_DLM=m, CONFIG_PROC_FS=n, and CONFIG_SYSFS=n, kernel build fails with: WARNING: "kernel_subsys" [fs/gfs2/locking/dlm/lock_dlm.ko] undefined!

* [DLM] Fix DLM configPatrick Caulfield2006-11-301-1/+2
| | | | | | | | | | | The attached patch fixes the DLM config so that it selects the chosen network transport. It should fix the bug where DLM can be left selected when NET gets unselected. This incorporates all the comments received about this patch.

* [DLM] Add support for tcp communicationsPatrick Caulfield2006-11-301-0/+17
| | | | | | | | | | | | The following patch adds a TCP based communications layer to the DLM which is compile time selectable. The existing SCTP layer gives the advantage of allowing multihoming, whereas the TCP layer has been heavily tested in previous versions of the DLM and is known to be robust and therefore can be used as a baseline for performance testing.

* [DLM] dlm: user locksDavid Teigland2006-07-131-8/+0
| | | | | | | | | | | | This changes the way the dlm handles user locks. The core dlm is now aware of user locks so they can be dealt with more efficiently. There is no more dlm_device module which previously managed its own duplicate copy of every user lock.

* [DLM] Update Kconfig in the light of comments on lkmlSteven Whitehouse2006-04-251-2/+1
| | | | | | | | | We now depend on user selectable options rather than select them. There is no dependancy on SYSFS since this selection is independant of the DLM (even though it wouldn't be sensible to build the DLM without it) Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
* [DLM] The core of the DLM for GFS2/CLVMDavid Teigland2006-01-181-0/+30
This is the core of the distributed lock manager which is required to use GFS2 as a cluster filesystem. It is also used by CLVM and can be used as a standalone lock manager independantly of either of these two projects. It implements VAX-style locking modes.
