2008-03-31[GFS2] Get rid of gl_waiters2Bob Peterson2-5/+6
This patch reduces memory by replacing the int variable gl_waiters2 by a single bit in the gl_flags. Signed-off-by: Bob Peterson <rpeterso@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2008-03-31[GFS2] Combine rg_flags and rd_flagsBob Peterson2-16/+26
This patch reduces the memory required by GFS2 by combining the rd_flags and rg_flags (in core only). Signed-off-by: Bob Peterson <rpeterso@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2008-03-31[GFS2] Allocate gfs2_rgrpd from slab memoryBob Peterson4-2/+14
This patch moves the gfs2_rgrpd structure to its own slab memory. This makes it easier to control and monitor, and yields less memory fragmentation. Signed-off-by: Bob Peterson <rpeterso@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

2008-03-31[GFS2] Misc fixupsBob Peterson2-5/+2
This patch contains two small fixups that didn't fit elsewhere. They are: (1) get rid of temp variable in find_metapath. (2) Remove vestigial "ret" variable from gfs2_writepage_common. Signed-off-by: Bob Peterson <rpeterso@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2008-03-31[GFS2] Only do lo_incore_commit onceBob Peterson4-29/+17
This patch is performance related. When we're doing a log flush, I noticed we were calling buf_lo_incore_commit twice: once for data bufs and once for metadata bufs. Since this is the same function and does the same thing in both cases, there should be no reason to call it twice. Since we only need to call it once, we can also make it faster by removing it from the generic "lops" code and making it a stand-along static function.

2008-03-31[GFS2] Fix debug inode printingBob Peterson1-1/+2
I noticed that the latest change to i_height got rid of the value from the inode dump. This patch adds it back. Signed-off-by: Bob Peterson <rpeterso@redhat.com> Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
2008-03-31[GFS2] Get rid of unneeded parameter in gfs2_rlist_allocBob Peterson5-10/+8

2008-03-31[GFS2] Streamline indirect pointer tree height calculationSteven Whitehouse5-83/+55
This patch improves the calculation of the tree height in order to reduce the number of operations which are carried out on each call to gfs2_block_map. In the common case, we now make a single comparison, rather than calculating the required tree height from scratch each time. Also in the case that the tree does need some extra height, we start from the current height rather from zero when we work out what the new height ought to be. In addition the di_height field is moved into the inode proper and reduced in size to a u8 since the value must be between 0 and GFS2_MAX_META_HEIGHT (10).

2008-03-31[GFS2] Speed up gfs2_write_alloc_required, deprecate gfs2_extent_mapSteven Whitehouse1-17/+19
This patch removes the call to gfs2_extent_map from gfs2_write_alloc_required, instead we call gfs2_block_map directly. This results in fewer overall calls to gfs2_block_map in the multi-block case. Also, gfs2_extent_map is marked as deprecated so that people know that its going away as soon as all the callers have been converted. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

These messages are a regression compared with 2.6.24, which did not flood the syslog with them. The actual underlying problem was introduced in 2.6.23, when somebody made the string parsing no longer accept nul-terminated strings as a valid input to store_uevent(). Eg. "add\0" was valid prior to 2.6.23, where the code regressed to require "add" without the '\0'. This patch fixes the 2.6.23 / 2.6.24 regressions, by having the code once again tolerate the trailing '\0', if present. According to GregKH, this mainly affects older Ubuntu systems, such as the one I have here that requires this fix.

2008-03-30evdev: Release eventual input device grabs when getting disconnectedBjörn Steinbrink1-0/+3
When getting disconnected we need to release eventual grabs on the underlying input device as we also release the input device itself. Otherwise, we would try to release the grab when the client that requested it closes its handle, accessing the input device which might already be freed.

2008-03-30drm: fix for non-coherent DMA PowerPCBenjamin Herrenschmidt3-6/+31
This patch fixes bits of the DRM so to make the radeon DRI work on non-cache coherent PCI DMA variants of the PowerPC processors. It moves the few places that needs change to wrappers to that other architectures with similar issues can easily add their own changes to those wrappers, at least until we have more useful generic kernel API.

2008-03-29Revert "ide: change master/slave IDENTIFY order"Bartlomiej Zolnierkiewicz2-2/+4
This reverts commit b140b99c413ce410197cfcd4014e757cd745226a. [ conflict in drivers/ide/ide-probe.c fixed manually ] It turned out that probing order change causes problems for some drives: http://bugzilla.kernel.org/show_bug.cgi?id=10239 Since root causes are still being investigated and are unlikely to be fixed before 2.6.25 lets revert this change for now. As a result cable detection becomes less reliable when compared with 2.6.24 but the affected drives are useable again.

There have been reported regressions of the SIL 680 driver when using MMIO, so this makes it only try MMIO on Cell blades where it's known to be necessary (the host bridge doesn't do PIO on these).
