btrfs: move btrfs_unlock_up_safe to other locking functions

2019-11-18T11:46:49+00:00

The function belongs to the family of locking functions, so move it
there. The 'noinline' keyword is dropped as it's now an exported
function that does not need it.

btrfs: make btrfs_assert_tree_locked static inline

2019-11-18T11:46:49+00:00

The function btrfs_assert_tree_locked is used outside of the locking
code so it is exported, however we can make it static inine as it's
fairly trivial.

This is the only locking assertion used in release builds, inlining
improves the text size by 174 bytes and reduces stack consumption in the
callers.

btrfs: Remove unused locking functions

2019-09-09T12:58:59+00:00

Those were split out of btrfs_clear_lock_blocking_rw by
aa12c02778a9 ("btrfs: split btrfs_clear_lock_blocking_rw to read and write helpers")
however at that time this function was unused due to commit
523983401644 ("Btrfs: kill btrfs_clear_path_blocking"). Put the final
nail in the coffin of those 2 functions.

btrfs: merge btrfs_set_lock_blocking_rw with it's caller

2019-02-25T13:13:28+00:00

The last caller that does not have a fixed value of lock is
btrfs_set_path_blocking, that actually does the same conditional swtich
by the lock type so we can merge the branches together and remove the
helper.

btrfs: open code now trivial btrfs_set_lock_blocking

2019-02-25T13:13:27+00:00

btrfs_set_lock_blocking is now only a simple wrapper around
btrfs_set_lock_blocking_write. The name does not bring any semantic
value that could not be inferred from the new function so there's no
point keeping it.

btrfs: replace btrfs_set_lock_blocking_rw with appropriate helpers

2019-02-25T13:13:27+00:00

We can use the right helper where the lock type is a fixed parameter.

btrfs: split btrfs_clear_lock_blocking_rw to read and write helpers

2019-02-25T13:13:27+00:00

There are many callers that hardcode the desired lock type so we can
avoid the switch and call them directly. Split the current function to
two. There are no remaining users of btrfs_clear_lock_blocking_rw so
it's removed.  The call sites will be converted in followup patches.

There are many callers that hardcode the desired lock type so we can
avoid the switch and call them directly. Split the current function to
two but leave a helper that still takes the variable lock type to make
current code compile.  The call sites will be converted in followup
patches.

btrfs: replace GPL boilerplate by SPDX -- headers

2018-04-12T14:29:46+00:00

Remove GPL boilerplate text (long, short, one-line) and keep the rest,
ie. personal, company or original source copyright statements. Add the
SPDX header.

Unify the include protection macros to match the file names.
