* [GFS2] Allow mounting of gfs2 and gfs2meta at the same timeAbhijith Das2006-08-254-3/+155
| | | | | | | | | | This patch allows the simultaneous mounting of gfs2meta and gfs2 filesystems. A restriction however is that a gfs2meta fs may only be mounted if its corresponding gfs2 filesystem is also mounted. Also, a gfs2 filesystem cannot be unmounted before its gfs2meta filesystem.

* [DLM] add new lockspace to list ealierDavid Teigland2006-08-252-6/+11
| | | | | | | | | | | | | When a new lockspace was being created, the recoverd thread was being started for it before the lockspace was added to the global list of lockspaces. The new thread was looking up the lockspace in the global list and sometimes not finding it due to the race with the original thread adding it to the list. We need to add the lockspace to the global list before starting the thread instead of after, and if the new thread can't find the lockspace for some reason, it should return an error.

* [GFS2] Fix journal off-by-one errorBenjamin Marzinski2006-08-251-1/+3
| | | | | | | | | | | | | | | log_refund() incorrectly assumed that if a transaction had been touched, it always committed buffers to the incore log. Thus, when you got around to flushing the log, you would need one more block than you committed, to account for the header. So it automatically set reserved to 1, which had the effect of making sdp->sd_log_blks_reserved one greater when you got to gfs2_log_flush(). However, if you don't actually commit anything to the incore log between flushes, you don't need the header, because you aren't writing anything out. With this patch, log_refund() only increments reservered to account for the header if something has been committed since the last flush. Signed-off-by: Benjamin E.

* [GFS2] Speed up scanning of glocksSteven Whitehouse2006-08-243-21/+5
| | | | | | | | | | | | | | | | | | I noticed the gfs2_scand seemed to be taking a lot of CPU, so in order to cut that down a bit, here is a patch. Firstly the type of a glock is a constant during its lifetime, so that its possible to check this without needing locking. I've moved the (common) case of testing for an inode glock outside of the glmutex lock. Also there was a mutex left over from when the glock cache was master of the inode cache. That isn't required any more so I've removed that too. There is probably scope for further speed ups in the future in this area. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
* [GFS2] Tidy up error handling in gfs2_releasepage()Steven Whitehouse2006-08-241-15/+14
| | | | | | | | This should clarify the logic in gfs2_releasepage() relating to error handling as well as making the response to errors a bit more graceful. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
* [DLM] recover_locks not clearing NEW_MASTER flagDavid Teigland2006-08-241-11/+0
| | | | | | | | | | When there are no locks on a resource, the recover_locks() function fails to clear the NEW_MASTER flag by going directly to out, missing the line that clears the flag. Signed-off-by: David Teigland <teigland@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
* [DLM] sequence number missing in not_ready replyDavid Teigland2006-08-241-0/+1

* [DLM] down conversion clearing flagsDavid Teigland2006-08-233-5/+7
| | | | | | | | | | | The down-conversion optimization was resulting in the lkb flags being cleared because the stub message reply had no flags value set. Copy the current flags into the stub message so they'll be copied back into the lkb as part of processing the fake reply. Also add an assertion to catch this error more directly if it exists elsewhere. Signed-off-by: David Teigland <teigland@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

* [GFS2] Fix leak of gfs2_bufdataSteven Whitehouse2006-08-184-11/+6
| | | | | | | | | | | This fixes a memory leak of struct gfs2_bufdata and also some problems in the ordered write handling code. It needs a bit more testing, but I believe that the reference counting of ordered write buffers should now be correct. This is aimed at fixing Red Hat bugzilla: #201028 and #201082 Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
* [DLM] move kmap to after spin_unlockDavid Teigland2006-08-111-1/+1

| | | | | | | | | | | | | | | | recovery.c add a brelse to deal with gfs2_replay_read_block being called twice on the same block. add a dput to drop the ref count on the root inode.

* [DLM] reject replies to old requestsDavid Teigland2006-08-092-4/+17
| | | | | | | | | | | | When recoveries are aborted by other recoveries we can get replies to status or names requests that we've given up on. This can cause problems if we're making another request and receive an old reply. Add a sequence number to status/names requests and reject replies that don't match.

* [GFS2] Fix lack of buffers in writepage bugSteven Whitehouse2006-08-081-2/+6
| | | | | | | | | | | | In some cases we can enter write page without there being buffers attached to the page. In this case the function to add gfs2_bufdata to the buffers fails sliently causing further failures down the stack. This fix ensures that we always add buffers in writepage if they didn't already exist (mmap is one way to trigger this). Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
