Btrfs: disk-io: replace root args iff only fs_info used

2015-02-16T17:48:43+00:00

This is the 3rd independent patch of a larger project to cleanup btrfs's internal usage of btrfs_root. Many functions take btrfs_root only to grab the fs_info struct. By requiring a root these functions cause programmer overhead. That these functions can accept any valid root is not obvious until inspection. This patch reduces the specificity of such functions to accept the fs_info directly. These patches can be applied independently and thus are not being submitted as a patch series. There should be about 26 patches by the project's completion. Each patch will cleanup between 1 and 34 functions apiece. Each patch covers a single file's functions. This patch affects the following function(s): 1) csum_tree_block 2) csum_dirty_buffer 3) check_tree_block_fsid 4) btrfs_find_tree_block 5) clean_tree_block Signed-off-by: Daniel Dressler Signed-off-by: David Sterba

btrfs: sink blocksize parameter to btrfs_find_create_tree_block

2014-12-12T17:07:21+00:00

Finally it's clear that the requested blocksize is always equal to nodesize, with one exception, the superblock. Superblock has fixed size regardless of the metadata block size, but uses the same helpers to initialize sys array/chunk tree and to work with the chunk items. So it pretends to be an extent_buffer for a moment, btrfs_read_sys_array is full of special cases, we're adding one more. Signed-off-by: David Sterba

btrfs: use slab for end_io_wq structures

2014-10-02T15:30:29+00:00

The structure is frequently reused. Rename it according to the slab name. Signed-off-by: David Sterba

btrfs: remove parameter blocksize from read_tree_block

2014-10-02T15:14:50+00:00

Errors in readahead are not fatal and ignored elsewhere in the code. Signed-off-by: David Sterba
