[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [PATCH v3 0/5] Make Big QEMU Lock naming consistent
v3:
- Rebase
- Define bql_lock() macro on a single line [Akihiko Odaki]
v2:
- Rename APIs bql_*() [PeterX]
- Spell out "Big QEMU Lock (BQL)" in doc comments [PeterX]
- Rename "iolock" variables in hw/remote/mpqemu-link.c [Harsh]
- Fix bql_auto_lock() indentation in Patch 2 [Ilya]
- "with BQL taken" -> "with the BQL taken" [Philippe]
- "under BQL" -> "under the BQL" [Philippe]
The Big QEMU Lock ("BQL") has two other names: "iothread lock" and "QEMU global
mutex". The term "iothread lock" is easily confused with the unrelated --object
iothread (iothread.c).
This series updates the code and documentation to consistently use "BQL". This
makes the code easier to understand.
Stefan Hajnoczi (5):
system/cpus: rename qemu_mutex_lock_iothread() to bql_lock()
qemu/main-loop: rename QEMU_IOTHREAD_LOCK_GUARD to BQL_LOCK_GUARD
qemu/main-loop: rename qemu_cond_wait_iothread() to
qemu_cond_wait_bql()
Replace "iothread lock" with "BQL" in comments
Rename "QEMU global mutex" to "BQL" in comments and docs
