btrfs: fix typos in comments and strings

2025-09-23T06:49:16+00:00

Annual typo fixing pass. Strangely codespell found only about 30% of what is in this patch, the rest was done manually using text spellchecker with a custom dictionary of acceptable terms. Reviewed-by: Neal Gompa Signed-off-by: David Sterba

btrfs: remove btrfs_clear_extent_bits()

2025-07-21T22:09:22+00:00

It's just a simple wrapper around btrfs_clear_extent_bit() that passes a NULL for its last argument (a cached extent state record), plus there is not counter part - we have a btrfs_set_extent_bit() but we do not have a btrfs_set_extent_bits() (plural version). So just remove it and make all callers use btrfs_clear_extent_bit() directly.

btrfs: use pgoff_t for page index variables

2025-07-21T21:58:05+00:00

Any conversion of offsets in the logical or the physical mapping space of the pages is done by a shift and the target type should be pgoff_t (type of struct page::index). Fix the locations where it's still unsigned long. Signed-off-by: David Sterba

btrfs: add btrfs prefix to free space tree exported functions

2025-07-21T21:58:02+00:00

A few of the free space tree exported functions have a 'btrfs_' prefix in their name, but most don't. Not only is this inconsistent, the preferred style is to have such a prefix, to avoid potential collisions in the future with other kernel code and offer a somewhat better readibility by making it obvious in calls sites that we are calling btrfs specific code. So add the 'btrfs_' prefix to all free space tree functions that are missing it. Reviewed-by: Boris Burkov Signed-off-by: Filipe Manana Reviewed-by: David Sterba Signed-off-by: David Sterba

btrfs: make extent_buffer_test_bit() return a boolean instead

2025-07-21T21:58:02+00:00

All the callers want is to determine if a bit is set and all of them call the function and do a double negation (!!) on its result to get a boolean. So change it to return a boolean and simplify callers. Reviewed-by: Boris Burkov Signed-off-by: Filipe Manana Reviewed-by: David Sterba Signed-off-by: David Sterba

btrfs: tree-log: add and rename extent bits for dirty_log_pages tree

2025-07-21T21:58:01+00:00

The dirty_log_pages tree is used for tree logging and marks extents based on log_transid. The bits could be renamed to resemble the LOG1/LOG2 naming used for the BTRFS_FS_LOG1_ERR bits. The DIRTY bit is renamed to LOG1 and NEW to LOG2. Signed-off-by: David Sterba

btrfs: convert the buffer_radix to an xarray

2025-05-15T12:30:50+00:00

In order to fully utilize xarray tagging to improve writeback we need to convert the buffer_radix to a proper xarray. This conversion is relatively straightforward as the radix code uses the xarray underneath. Using xarray directly allows for quite a lot less code.

btrfs: use unsigned types for constants defined as bit shifts

2025-05-15T12:30:48+00:00

The unsigned type is a recommended practice (CWE-190, CWE-194) for bit shifts to avoid problems with potential unwanted sign extensions. Although there are no such cases in btrfs codebase, follow the recommendation. Reviewed-by: Boris Burkov Signed-off-by: David Sterba

btrfs: rename remaining exported extent map functions

2025-05-15T12:30:45+00:00

Rename all the exported functions from extent_map.h that don't have a 'btrfs_' prefix in their names, so that they are consistent with all the other functions, to make it clear they are btrfs specific functions and to avoid potential name collisions in the future with functions defined elsewhere in the kernel.

btrfs: rename functions to allocate and free extent maps

2025-05-15T12:30:45+00:00

These functions are exported and don't have a 'btrfs_' prefix in their names, which goes against coding style conventions. Rename them to have such prefix, making it clear they are from btrfs and avoiding potential collisions in the future with functions defined elsewhere outside btrfs.
