[00/13] dm vdo: clean up and simplify thread utilities

Message

Matthew Sakai March 1, 2024, 3:52 a.m. UTC

Rename uds-threads to thread-utils, and simplify thread and
synchronization utilities. Move some utilities closer to their
only users.

Mike Snitzer (13):
  dm vdo: make uds_*_semaphore interface private to uds-threads.c
  dm vdo uds-threads: eliminate uds_*_semaphore interfaces
  dm vdo uds-threads: push 'barrier' down to sparse-cache
  dm vdo indexer sparse-cache: cleanup threads_barrier code
  dm vdo: rename uds-threads.[ch] to thread-utils.[ch]
  dm vdo indexer: rename uds.h to indexer.h
  dm vdo: fold thread-cond-var.c into thread-utils
  dm vdo thread-utils: push uds_*_cond interface down to indexer
  dm vdo thread-utils: remove all uds_*_mutex wrappers
  dm vdo thread-utils: further cleanup of thread functions
  dm vdo thread-utils: cleanup included headers
  dm vdo thread-registry: rename all methods to reflect vdo-only use
  dm vdo thread-device: rename all methods to reflect vdo-only use
