* [GFS2] Map multiple blocks at once where possibleSteven Whitehouse2006-09-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a tidy up of the GFS2 bmap code. The main change is that the bh is passed to gfs2_block_map allowing the flags to be set directly rather than having to repeat that code several times in ops_address.c. At the same time, the extent mapping code from gfs2_extent_map has been moved into gfs2_block_map. This allows all calls to gfs2_block_map to map extents in the case that no allocation is taking place. As a result reads and non-allocating writes should be faster. A quick test with postmark appears to support this. There is a limit on the number of blocks mapped in a single bmap call in that it will only ever map blocks which are pointed to from a single pointer block. So in other words, it will never try to do additional i/o in order to satisfy read-ahead. The maximum number of blocks is thus somewhat less than 512 (the GFS2 4k block size minus the header divided by sizeof(u64)). I've further limited the mapping of "normal" blocks to 32 blocks (to avoid extra work) since readpages() will currently read a maximum of 32 blocks ahead (128k). Some further work will probably be needed to set a suitable value for DIO as well, but for now thats left at the maximum 512 (see ops_address.c:gfs2_get_block_direct). There is probably a lot more that can be done to improve bmap for GFS2, but this is a good first step. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>

This is very important during the migration phase for V4L2 API. However, userspace apps should be capable of using both APIs, since they need to test at runtime, via VIDIOCGCAP ioctl, if V4L1 is supported. So, when __KERNEL__ is not defined, those ioctls and corresponding structs should be visible. This patch also removes the obsolete defines HAVE_V4L1 and HAVE_V4L2, that where causing some confusion, and were replaced by CONFIG_VIDEO_V4L1_COMPAT and CONFIG_VIDEO_V4L2.

With current toolchains, this is no longer the case, and the syntax magically changed as well, causing all current toolchains to die a horrible death. Incidentally, code generation in other parts of the kernel is now significantly complex enough that none of the older toolchains make it very far these days, so there's not even any point in preserving legacy compatability via as-option. This fixes a long-standing issue, as noted here: http://lkml.org/lkml/2005/1/5/223 Though at the time the current toolchains were too broken to make adjusting the tuning worthwhile.

The fix could cause xfssyncd to loop endlessly if we did not leave some space free for the allocator to work correctly. Basically, we needed to ensure that we had at least 4 blocks free for an AG free list and a block for the inode bmap btree at all times. However, this did not take into account the fact that each AG has a free list that needs 4 blocks. Hence any filesystem with more than one AG could cause oversubscription of free space and make xfssyncd spin forever trying to allocate space needed for AG freelists that was not available in the AG. The following patch reserves space for the free lists in all AGs plus the inode bmap btree which prevents oversubscription. It also prevents those blocks from being reported as free space (as they can never be used) and makes the SMP in-core superblock accounting code and the reserved block ioctl respect this requirement.

It seems, that previous solution based on 16 bytes (FIFO length size) read is still timing sensitive on genirq and fully preemptive kernels. The new solution is backuped by M9328 UM statement, that only 512 byte block are working properly and by 2.4.26 FreeScale's SDHC code. Jay Monkman reports significant improvement on code based on this driver after applying this change on MX21 as well.
