This patch further reduces the memory needs of GFS2 by eliminating the gl_req_bh variable from struct gfs2_glock. Signed-off-by: NBob Peterson <rpeterso@redhat.com> Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

There are a couple of routines which scan bitmaps where we can mark the bitmaps const, plus a couple of call sites that can be updated too. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

The reason for doing this is to allow all the block mapping code to share the same array. As a result we can remove two arguments from lookup_metapath since they are now returned via the array. We also add a function to drop all refs to buffer heads when we are done with the metapath. The build_height function shares the struct metapath, but currently still frees its own buffers, and this will change in a future patch. Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

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: NBob Peterson <rpeterso@redhat.com> Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

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: NBob Peterson <rpeterso@redhat.com> Signed-off-by: NSteven Whitehouse <swhiteho@redhat.com>

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.

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).

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: NSteven 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.

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.
