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: NSteven Whitehouse <swhiteho@redhat.com>

Two internal files which are read through the gfs2_internal_read() routine were already locked when the routine was called and this do not need locking at the redapages level. This patch introduces a struct file which is used as a sentinal so that readpage will only perform locking in the case that the struct file passed to it is _not_ equal to this sentinal. Since the comments in the generic kernel code indicate that the struct file will never be used for anything other than passing straight through to readpage(), this should be ok.

This patch adds back O_DIRECT support with various caveats attached: 1. Journaled data can be read via O_DIRECT since its now the same on disk format as normal data files. 2. Journaled data writes with O_DIRECT will be failed sliently back to normal writes (should we really do this I wonder or should we return an error instead?) 3. Stuffed files will be failed back to normal buffered I/O 4. All the usual corner cases (write beyond current end of file, write to an unallocated block) will also revert to normal buffered I/O. The I/O path is slightly odd as reads arrive at the page cache layer with the lock for the file already held, but writes arrive unlocked. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

There were one or two fields in structures which didn't get changed last time back to their gfs1 sizes and alignments. One or two constants have also changed back to their original values which were missed the first time. Its possible that indirect pointer blocks might need to change. If they don't we'll have to rewrite them all on upgrade due to a change in the amount of padding that they use. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

Umount is now working correctly again. The bug was due to not getting an extra ref count when mounting the fs. We should have bumped it by two (once for the internal pointer to the root inode from the super block and once for the inode hanging off the dcache entry for root). Also this patch tidys up the code dealing with looking up and creating inodes. We now pass Linux inodes (with gfs2_inodes attached) rather than the other way around and this reduces code duplication in various places. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

This is a very large patch, with a few still to be resolved issues so you might want to check out the previous head of the tree since this is known to be unstable. Fixes for the various bugs will be forthcoming shortly. This patch removes the special data format which has been used up till now for journaled data files. Directories still retain the old format so that they will remain on disk compatible with earlier releases. As a result you can now do the following with journaled data files: 1) mmap them 2) export them over NFS 3) convert to/from normal files whenever you want to (the zero length restriction is gone) In addition the level at which GFS' locking is done has changed for all files (since they all now use the page cache) such that the locking is done at the page cache level rather than the level of the fs operations. This should mean that things like loopback mounts and other things which touch the page cache directly should now work. Current known issues: 1. There is a lock mode inversion problem related to the resource group hold function which needs to be resolved. 2. Any significant amount of I/O causes an oops with an offset of hex 320 (NULL pointer dereference) which appears to be related to a journaled data buffer appearing on a list where it shouldn't be. 3. Direct I/O writes are disabled for the time being (will reappear later) 4. There is probably a deadlock between the page lock and GFS' locks under certain combinations of mmap and fs operation I/O. 5. Issue relating to ref counting on internally used inodes causes a hang on umount (discovered before this patch, and not fixed by it) 6. One part of the directory metadata is different from GFS1 and will need to be resolved before next release. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

Update the function in GFS2 which deals with truncation of partial blocks. Some of the code is "borrowed" from ext3 since it appears to give a good model of how to do this operation. The function is renamed gfs2_block_truncate_page accordingly. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

Add the new external read function. Its temporarily in jdata.c even though the protoype is in ops_file.h - this will change shortly. The current implementation will change to a page cache one when that happens. In order to effect the above changes, the various internal inodes now have Linux inodes attached to them. We keep the references to the Linux inodes, rather than the gfs2_inodes in the super block. In order to get everything to work correctly I've had to reorder the init sequence on mount (which I should probably have done earlier when .gfs2_admin was made visible).

The compat layer timeout handling changes in: 9f72949f are busted. This is most easily seen with an X application that uses sub-second select/poll timeout such as emacs. You hit a key and it takes a second or so before the app responds. The two ROUND_UP() calls upon entry are using {tv,ts}_sec where it should instead be using {tv_usec,ts_nsec}, which perfectly explains the observed incorrect behavior.

This is a subset of the bluesmoke project core code, stripped of the NMI work which isn't ready to merge and some of the "interesting" proc functionality that needs reworking or just has no place in kernel. It requires no core kernel changes except the added scrub functions already posted. The goal is to merge further functionality only after the core code is accepted and proven in the base kernel, and only at the point the upstream extras are really ready to merge. From: doug thompson <norsk5@xmission.com> This converts EDAC to sysfs and is the final chunk neccessary before EDAC has a stable user space API and can be considered for submission into the base kernel.

EDAC requires a way to scrub memory if an ECC error is found and the chipset does not do the work automatically. That means rewriting memory locations atomically with respect to all CPUs _and_ bus masters. That means we can't use atomic_add(foo, 0) as it gets optimised for non-SMP This adds a function to include/asm-foo/atomic.h for the platforms currently supported which implements a scrub of a mapped block. It also adjusts a few other files include order where atomic.h is included before types.h as this now causes an error as atomic_scrub uses u32.
