The following commit has been merged into the locking/core branch of tip: Commit-ID: 6988631bdfddcedc1d27f83723ea36a442f00ea1 Gitweb: https://git.kernel.org/tip/6988631bdfddcedc1d27f83723ea36a442f00ea1 Author: Mark Rutland <mark.rutland@xxxxxxx> AuthorDate: Tue, 25 May 2021 15:02:10 +01:00 Committer: Peter Zijlstra <peterz@xxxxxxxxxxxxx> CommitterDate: Wed, 26 May 2021 13:20:50 +02:00 locking/atomic: cmpxchg: make `generic` a prefix The asm-generic implementations of cmpxchg_local() and cmpxchg64_local() use a `_generic` suffix to distinguish themselves from arch code or wrappers used elsewhere. Subsequent patches will add ARCH_ATOMIC support to these implementations, and will distinguish more functions with a `generic` portion. To align with how ARCH_ATOMIC uses an `arch_` prefix, it would be helpful to use a `generic_` prefix rather than a `_generic` suffix. In preparation for this, this patch renames the existing functions to make `generic` a prefix rather than a suffix. There should be no functional change as a result of this patch.
