2006-09-19[GFS2] Export lm_interface to kernel headersFabio Massimo Di Nitto1-1/+1
lm_interface.h has a few out of the tree clients such as GFS1 and userland tools. Right now, these clients keeps a copy of the file in their build tree that can go out of sync. Move lm_interface.h to include/linux, export it to userland and clean up fs/gfs2 to use the new location. Signed-off-by: Fabio M.

2006-09-05[GFS2] More style fixesSteven Whitehouse1-1/+1
As per Jan Engelhardt's follow up emails, here are a few small fixes which were missed earlier. Cc: Jan Engelhardt <jengelh@linux01.gwdg.de> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-09-05[GFS2] Fix end of multi-line structuresSteven Whitehouse1-8/+8
As per Jan Engelhardt's request, I've added a ',' to the end of each of the multi-line structures which didn't already have one (most already did). Cc: Jan Engelhardt <jengelh@linux01.gwdg.de> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-09-04[GFS2] Change all types to uX styleSteven Whitehouse1-2/+2
This makes all fixed size types have consistent names. Cc: Jan Engelhardt <jengelh@linux01.gwdg.de> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

2006-09-01[GFS2] Update copyright, tidy up incore.hSteven Whitehouse1-1/+1
As per comments from Jan Engelhardt <jengelh@linux01.gwdg.de> this updates the copyright message to say "version" in full rather than "v.2". Also incore.h has been updated to remove forward structure declarations which are not required. The gfs2_quota_lvb structure has now had endianess annotations added to it. Also quota.c has been updated so that we now store the lvb data locally in endian independant format to avoid needing a structure in host endianess too. As a result the endianess conversions are done as required at various points and thus the conversion routines in lvb.[ch] are no longer required. I've moved the one remaining constant in lvb.h thats used into lm.h and removed the unused lvb.[ch]. I have not changed the HIF_ constants. That is left to a later patch which I hope will unify the gh_flags and gh_iflags fields of the struct gfs2_holder.

2006-06-14[GFS2] Fix unlinked file handlingSteven Whitehouse1-2/+0
This patch fixes the way we have been dealing with unlinked, but still open files. It removes all limits (other than memory for inodes, as per every other filesystem) on numbers of these which we can support on GFS2. It also means that (like other fs) its the responsibility of the last process to close the file to deallocate the storage, rather than the person who did the unlinking. Note that with GFS2, those two events might take place on different nodes. Also there are a number of other changes: o We use the Linux inode subsystem as it was intended to be used, wrt allocating GFS2 inodes o The Linux inode cache is now the point which we use for local enforcement of only holding one copy of the inode in core at once (previous to this we used the glock layer). o We no longer use the unlinked "special" file. We just ignore it completely. This makes unlinking more efficient. o We now use the 4th block allocation state. The previously unused state is used to track unlinked but still open inodes. o gfs2_inoded is no longer needed o Several fields are now no longer needed (and removed) from the in core struct gfs2_inode o Several fields are no longer needed (and removed) from the in core superblock There are a number of future possible optimisations and clean ups which have been made possible by this patch.

2006-05-18[GFS2] Remove semaphore.h from C filesSteven Whitehouse1-1/+0
We no longer use semaphores, everything has been converted to mutex or rwsem, so we don't need to include this header any more. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2006-02-27[GFS2] Macros removal in gfs2.hSteven Whitehouse1-0/+4
As suggested by Pekka Enberg <penberg@cs.helsinki.fi>. The DIV_RU macro is renamed DIV_ROUND_UP and and moved to kernel.h The other macros are gone from gfs2.h as (although not requested by Pekka Enberg) are a number of included header file which are now included individually. The inode number comparison function is now an inline function. The DT2IF and IF2DT may be addressed in a future patch. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

2006-02-21[GFS2] Use mutices rather than semaphoresSteven Whitehouse1-2/+2
As well as a number of minor bug fixes, this patch changes GFS to use mutices rather than semaphores. This results in better information in case there are any locking problems. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
