This patch makes\nthings much less complicated by only unpinning the extent if the block group is\ncached. We check the block_group-\u003ecached var under the block_group-\u003elock spin\nlock. If it is set to BTRFS_CACHE_FINISHED then we update the pinned counters,\nand unpin the extent and add the free space back. If it is not set to this, we\nstart the caching of the block group so the next time we unpin extents we can\nunpin the extent. This keeps us from racing with the async caching threads,\nlets us kill the fs wide async thread counter, and keeps us from having to set\nDELALLOC bits for every extent we hit if there are caching kthreads going.\n\nOne thing that needed to be changed was btrfs_free_super_mirror_extents.

Instead of blocking up behind the caching\nmutex, we instead kick of the caching kthread, and then attempt to make an\nallocation. If we cannot, we wait on the block groups caching waitqueue, which\nthe caching kthread will wake the waiting threads up everytime it finds 2 meg\nworth of space, and then again when its finished caching.

This doesn\u0027t really change anything else as far as the\npinned extent map is concerned, since for actual pinned extents we use\nEXTENT_DIRTY, but it does mean that when we unmount we have to go in and unlock\nthose extents to keep from leaking memory.\n\nI\u0027ve also added a check where when we are reading block groups from disk, if the\namount of space used \u003d\u003d the size of the block group, we go ahead and mark the\nblock group as cached.

As free space gets fragmented, we end up with thousands of\nentries on an rb-tree per block group, which usually spans 1 gig of area. Since\nwe currently don\u0027t ever flush free space cache back to disk this gets to be a\nbit unweildly on large fs\u0027s with lots of fragmentation.\n\nThis patch solves this problem by using PAGE_SIZE bitmaps for parts of the free\nspace cache. Initially we calculate a threshold of extent entries we can\nhandle, which is however many extent entries we can cram into 16k of ram. The\nmaximum amount of RAM that should ever be used to track 1 gigabyte of diskspace\nwill be 32k of RAM, which scales much better than we did before.\n\nOnce we pass the extent threshold, we start adding bitmaps and using those\ninstead for tracking the free space. This patch also makes it so that any free\nspace thats less than 4 * sectorsize we go ahead and put into a bitmap. This is\nnice since we try and allocate out of the front of a block group, so if the\nfront of a block group is heavily fragmented and then has a huge chunk of free\nspace at the end, we go ahead and add the fragmented areas to bitmaps and use a\nnormal extent entry to track the big chunk at the back of the block group.\n\nI\u0027ve also taken the opportunity to revamp how we search for free space.\nPreviously we indexed free space via an offset indexed rb tree and a bytes\nindexed rb tree. I\u0027ve dropped the bytes indexed rb tree and use only the offset\nindexed rb tree. This cuts the number of tree operations we were doing\npreviously down by half, and gives us a little bit of a better allocation\npattern since we will always start from a specific offset and search forward\nfrom there, instead of searching for the size we need and try and get it as\nclose as possible to the offset we want.\n\nI\u0027ve given this a healthy amount of testing pre-new format stuff, as well as\npost-new format stuff. I\u0027ve booted up my fedora box which is installed on btrfs\nwith this patch and ran with it for a few days without issues. I\u0027ve not seen\nany performance regressions in any of my tests.\n\nSince the last patch Yan Zheng fixed a problem where we could have overlapping\nentries, so updating their offset inline would cause problems.

That can lead to a filesystem corruption\nif we crash at the right moment.
