Subject: [PATCH v3] bitops: use common function parameter names
Date: Thu, 30 Apr 2026 21:59:23 -0700	[thread overview]
Message-ID: <20260501045923.2884548-1-rdunlap@infradead.org> (raw)

Fix the function prototypes to use the common parameter name 'addr'
instead of 'p' (common to arch-specific implementations of these
functions).
This avoids the kernel-doc warnings:

Warning: include/asm-generic/bitops/lock.h:19 function parameter 'p'
 not described in 'arch_test_and_set_bit_lock'
Warning: include/asm-generic/bitops/lock.h:41 function parameter 'p'
 not described in 'arch_clear_bit_unlock'
Warning: include/asm-generic/bitops/lock.h:59 function parameter 'p'
 not described in 'arch___clear_bit_unlock'

Fixes: 84c6591103db ("locking/atomics, asm-generic/bitops/lock.h: Rewrite using atomic_fetch_*()")
Signed-off-by: Randy Dunlap <rdunlap@infradead.org>
---
v2: rebase & resend
v3: change the function parameter names instead of the kernel-doc
    comments (Yury) (Fixes: can be kept or dropped at maintainer discretion.)
