A recent change in kernel/acct.c added a new warning for many configurations on ARM: kernel/acct.c: In function 'acct_pin_kill': arch/arm/include/asm/cmpxchg.h:122:3: warning: value computed is not used [-Wunused-value] The code is in fact correct, it's just a cmpxchg() call that intentionally ignores the result, and no other code does that. The warning does not show up on x86 because of the way that its cmpxchg() macro is written. This changes the ARM implementation to use a similar construct with a compound expression instead of a typecast, which causes the compiler to not complain about an unused result. Fix the other macros in this file in a similar way, and place them just below their function implementations. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk> |
