Btrfs: fix scrub_print_warning to handle skinny metadata extents

2014-07-02T10:06:40+00:00

commit 6eda71d0c030af0fc2f68aaa676e6d445600855b upstream. The skinny extents are intepreted incorrectly in scrub_print_warning(), and end up hitting the BUG() in btrfs_extent_inline_ref_size.

Btrfs: allocate prelim_ref with a slab allocater

2013-09-01T12:16:27+00:00

struct __prelim_ref is allocated and freed frequently when walking backref tree, using slab allocater can not only speed up allocating but also detect memory leaks. Signed-off-by: Wang Shilong Reviewed-by: Miao Xie Reviewed-by: Jan Schmidt Signed-off-by: Josef Bacik Signed-off-by: Chris Mason

Btrfs: cleanup backref search commit root flag stuff

2013-07-01T12:52:29+00:00

Looking into this backref problem I noticed we're using a macro to what turns out to essentially be a NULL check to see if we need to search the commit root. I'm killing this, let's just do what everybody else does and checks if trans == NULL. I've also made it so we pass in the path to __resolve_indirect_refs which will have the search_commit_root flag set properly already and that way we can avoid allocating another path when we have a perfectly good one to use.

btrfs: make static code static & remove dead code

2013-05-06T19:55:23+00:00

Big patch, but all it does is add statics to functions which are in fact static, then remove the associated dead-code fallout. removed functions: btrfs_iref_to_path() __btrfs_lookup_delayed_deletion_item() __btrfs_search_delayed_insertion_item() __btrfs_search_delayed_deletion_item() find_eb_for_page() btrfs_find_block_group() range_straddles_pages() extent_range_uptodate() btrfs_file_extent_length() btrfs_scrub_cancel_devid() btrfs_start_transaction_lflush() btrfs_print_tree() is left because it is used for debugging. btrfs_start_transaction_lflush() and btrfs_reada_detach() are left for symmetry. ulist.c functions are left, another patch will take care of those.

Btrfs: move fs/btrfs/ioctl.h to include/uapi/linux/btrfs.h

2013-02-20T14:37:28+00:00

The header file will then be installed under /usr/include/linux so that userspace applications can refer to Btrfs ioctls by name and use the same structs used internally in the kernel. Signed-off-by: Filipe Brandenburger Signed-off-by: Josef Bacik

Btrfs: extended inode refs support for send mechanism

This adds support for the new extended inode refs to btrfs send. Signed-off-by: Jan Schmidt

btrfs: extended inode ref iteration

2012-10-09T13:15:01+00:00

The iterate_irefs in backref.c is used to build path components from inode refs. This patch adds code to iterate extended refs as well. I had modify the callback function signature to abstract out some of the differences between ref structures. iref_to_path() also needed similar changes. Signed-off-by: Mark Fasheh

btrfs: extended inode refs

2012-10-09T13:14:45+00:00

This patch adds basic support for extended inode refs. This includes support for link and unlink of the refs, which basically gets us support for rename as well. Inode creation does not need changing - extended refs are only added after the ref array is full. Signed-off-by: Mark Fasheh

Btrfs: fix a bug in parsing return value in logical resolve

2012-10-01T19:19:18+00:00

In logical resolve, we parse extent_from_logical()'s 'ret' as a kind of flag. It is possible to lose our errors because (-EXXXX & BTRFS_EXTENT_FLAG_TREE_BLOCK) is true. I'm not sure if it is on purpose, it just looks too hacky if it is. I'd rather use a real flag and a 'ret' to catch errors. Acked-by: Jan Schmidt Signed-off-by: Liu Bo
