Date: Thu, 18 May 2017 11:38:25 +0800	[thread overview]
Message-ID: <20170518033857.15002-1-quwenruo@cn.fujitsu.com> (raw)

The patchset can be fetched from my github:
https://github.com/adam900710/btrfs-progs/tree/fs_info_refactor

Which is based on v4.11-rc1.

This quite scary patchset does a large refactoring (while still less than
500 LoC) to move sector/node/stripe size members from btrfs_root to
btrfs_fs_info.
(Patch 2~29)

Also, refactor some functions which only uses btrfs_root parameter for
block sizes. (Path 30~32)
Refactored functions are:
1) read_tree_block() in disk-io.c
2) corrupt_keys() in btrfs-corrupt-block.c
3) corrupt_metadata_block() in btrfs-corrupt-block.c
4) read_node_slot() in ctree.c

Such refactoring has already been done in kernel for some time.

I'm pretty sure there are still quite some remaining, but I'd like to
put them after this large patchset get merged.

I have run test-fsck, test-convert (despite the quotation error) and
test-misc. They all finished without problem.

Despite the refactoring, I also synchronized the definition of
btrfs_super_block, to make leafsize deprecated.
(Patch 1)

And less than 3 open-coded round_up are also refactored to round_up()
macro.
