Btrfs: Add backing store, memory management Signed-off-by: Chris Mason <chris.mason@oracle.com> 2007-02-02 09:18:22 -05:00
Btrfs: Fix makefile for builing btrfs static This fixes the btrfs makefile for building in the tree and out of the tree both as a module and static. Signed-off-by: Chris Mason <chris.mason@oracle.com> 2008-10-09 11:52:35 -04:00			`obj-$(CONFIG_BTRFS_FS) := btrfs.o`
Btrfs: simplify makefile Get rid of the hacks for building out of tree, and always use += for assigning to the object lists. Signed-off-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Chris Mason <chris.mason@oracle.com> 2009-04-13 15:32:28 +02:00

Switch btrfs_name_hash() to crc32c Date: Tue, 19 Aug 2008 19:21:57 +0100 Using a 64-bit hash as the readdir cookie is just asking for trouble. And gets it, when we try to export the file system by NFS.

Btrfs: add and improve comments This improves the comments at the top of many functions. It didn't dive into the guts of functions because I was trying to avoid merging problems with the new allocator and back reference work. extent-tree.c and volumes.c were both skipped, and there is definitely more work todo in cleaning and commenting the code.

Btrfs: Split the extent_map code into two parts There is now extent_map for mapping offsets in the file to disk and extent_io for state tracking, IO submission and extent_bufers. The new extent_map code shifts from [start,end] pairs to [start,len], and pushes the locking out into the caller. This allows a few performance optimizations and is easier to use. A number of extent_map usage bugs were fixed, mostly with failing to remove extent_map entries when changing the file.

Btrfs: Add a leaf reference cache Much of the IO done while dropping snapshots is done looking up leaves in the filesystem trees to see if they point to any extents and to drop the references on any extents found. This creates a cache so that IO isn't required. Signed-off-by: Chris Mason <chris.mason@oracle.com> 2008-07-28 15:32:19 -04:00			`extent_io.o volumes.o async-thread.o ioctl.o locking.o orphan.o \`
btrfs: Add lzo compression support Lzo is a much faster compression algorithm than gzib, so would allow more users to enable transparent compression, and some users can choose from compression ratio and speed for different applications Usage: # mount -t btrfs -o compress[=<zlib,lzo>] dev /mnt or # mount -t btrfs -o compress-force[=<zlib,lzo>] dev /mnt "-o compress" without argument is still allowed for compatability. Compatibility: If we mount a filesystem with lzo compression, it will not be able be mounted in old kernels. One reason is, otherwise btrfs will directly dump compressed data, which sits in inline extent, to user. Performance: The test copied a linux source tarball (~400M) from an ext4 partition to the btrfs partition, and then extracted it. (time in second) lzo zlib nocompress copy: 10.6 21.7 14.9 extract: 70.1 94.4 66.6 (data size in MB) lzo zlib nocompress copy: 185.87 108.69 394.49 extract: 193.80 132.36 381.21 Changelog: v1 -> v2: - Select LZO_COMPRESS and LZO_DECOMPRESS in btrfs Kconfig. - Add incompability flag. - Fix error handling in compress code.
