Red Hat BZ 213682 If two nodes leave the lockspace (while unmounting the fs in the case of gfs) after one has sent a STATUS message to the other, STATUS/STATUS_REPLY messages will then ping-pong between the nodes when neither of them can find the lockspace in question any longer. We kill this by not sending another STATUS message when we get a STATUS_REPLY for an unknown lockspace.

Red Hat BZ 213684 If a node sends an lkb to the new master (RCOM_LOCK message) during recovery and recovery is then aborted on both nodes before it gets a reply, the res_recover_locks_count needs to be reset to 0 so that when the subsequent recovery comes along and sends the lkb to the new master again the assertion doesn't trigger that checks that counter is zero.

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.

Stuffed files only consist of a maximum of (gfs2 block size - sizeof(struct gfs2_dinode)) bytes. Since the gfs2 block size is always less than page size, we will never see a call to stuffed_readpage for anything other than the first page in the file.

The log lock is dropped prior to io submittion, but this exposes a hole in which the log data structures may be going away due to a truncate. Store the buffer head in a local pointer prior to dropping the lock and relay on the buffer_head lock for consitency on the buffer head.

This function wasn't really doing the right thing. There was no need to update the inode size at this point and the updating of the i_blocks field has now been moved to the places where di_blocks is updated. A result of this patch and some those preceeding it is that unlocking a glock is now a much more efficient process, since there is no longer any requirement to copy data from the gfs2 inode into the vfs inode at this point.

Since the inode number is constant, we don't need to keep updating it everytime we refresh the other inode fields. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

We were setting the inode flags from GFS2's flags far too often, even when they couldn't possibly have changed. This patch reduces the amount of flag setting going on so that we do it only when the inode is read in or when the flags have changed. The create case is covered by the "when the inode is read in" case. This also fixes a bug where we didn't set S_SYNC correctly. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

This fixes a race between the glock and the page lock encountered during truncate in gfs2_readpage and gfs2_prepare_write. The gfs2_readpages function doesn't need the same fix since it only uses a try lock anyway, so it will fail back to gfs2_readpage in the case of a potential deadlock. This bug was spotted by Russell Cattelan. Cc: Russell Cattelan <cattelan@redhat.com> Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

There is no way to set the GL_DUMP flag, and in any case the same thing can be done with systemtap if required for debugging, so this removes it. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

The meta_header for an ondisk rgrp never changes, so there is no point copying it in and back out to disk. Also there is no reason to keep a copy for each rgrp in memory. The code already checks to ensure that the header is correct before it calls the routine to copy the data in, so that we don't even need to check whether its correct on disk in the functions in ondisk.c Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

This shrinks the size of the gfs2_inode by 8 bytes by replacing the version counter with a one bit valid/invalid flag. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

This is almost never used. Its there for backward compatibility with GFS1. It doesn't need its own field since it can always be calculated from the inode mode & flags. This saves a bit more space in the gfs2_inode. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

The metadata header doesn't need to be stored in the incore struct gfs2_inode since its constant, and this patch removes it. Also, there is already a field for the inode's number in the struct gfs2_inode, so we don't need one in struct gfs2_dinode_host as well. This saves 28 bytes of space in the struct gfs2_inode.

Everywhere this was called, a struct gfs2_inode was available, but despite that, it was always called with a struct gfs2_dinode as an argument. By making this change it paves the way to start eliminating fields duplicated between the kernel's struct inode and the struct gfs2_dinode. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

The latter is used as part of gfs2-private part of struct inode. It actually stores a lot of fields differently; for now the declaration is just cloned, inode field is swtiched and changes propagated.
