btrfs: drop unused parameter path from btrfs_tree_mod_log_rewind()

2024-11-11T13:34:15+00:00

The path parameter was used for our own locking, that got converted to rwsem eventually. Last usage in ac5887c8e013d6 ("btrfs: locking: remove all the blocking helpers"). Reviewed-by: Anand Jain Signed-off-by: David Sterba

btrfs: constify more pointer parameters

2024-09-10T14:51:22+00:00

Continue adding const to parameters. This is for clarity and minor addition to safety. There are some minor effects, in the assembly code and .ko measured on release config. Signed-off-by: David Sterba

btrfs: add forward declarations and headers, part 1

2024-03-04T15:24:49+00:00

Do a cleanup in the short headers: - add forward declarations for types referenced by pointers - add includes when types need them This fixes potential compilation problems if the headers are reordered or the missing includes are not provided indirectly. Signed-off-by: David Sterba

btrfs: fix SPDX comment in tree-mod-log.h

2022-12-05T17:00:48+00:00

The header files should use the /* */ comment style, introduced in commit f3a84ccd28d0 ("btrfs: move the tree mod log code into its own file"). Signed-off-by: David Sterba

btrfs: remove gfp_t flag from btrfs_tree_mod_log_insert_key()

2022-12-05T17:00:40+00:00

All callers of btrfs_tree_mod_log_insert_key() are now passing a GFP_NOFS flag to it, so remove the flag from it and from alloc_tree_mod_elem() and use it directly within alloc_tree_mod_elem(). Signed-off-by: Filipe Manana Reviewed-by: David Sterba Signed-off-by: David Sterba

btrfs: add and use helper to get lowest sequence number for the tree mod log

2021-04-19T15:25:17+00:00

There are two places outside the tree mod log module that extract the lowest sequence number of the tree mod log. These places end up duplicating code and open coding the logic and internal implementation details of the tree mod log. So add a helper to the tree mod log module and header that returns the lowest sequence number or 0 if there aren't any tree mod log users at the moment.

btrfs: use booleans where appropriate for the tree mod log functions

2021-04-19T15:25:16+00:00

Several functions of the tree modification log use integers as booleans, so change them to use booleans instead, making their use more clear. Reviewed-by: Anand Jain Signed-off-by: Filipe Manana Reviewed-by: David Sterba Signed-off-by: David Sterba

btrfs: move the tree mod log code into its own file

2021-04-19T15:25:16+00:00

The tree modification log, which records modifications done to btrees, is quite large and currently spread all over ctree.c, which is a huge file already. To make things better organized, move all that code into its own separate source and header files. Functions and definitions that are used outside of the module (mostly by ctree.c) are renamed so that they start with a "btrfs_" prefix. Everything else remains unchanged. This makes it easier to go over the tree modification log code every time I need to go read it to fix a bug.
