Comment in include/linux/spinlock.h says: * here's the role of the various spinlock/rwlock related include * files: * * on SMP builds: * [...] * asm/spinlock.h: contains the arch_spin_*()/etc. lowlevel * implementations, mostly inline assembly code * This, and the fact that include/asm-generic/spinlock.h and arch/arm64/include/asm/spinlock.h doesn't prevent the direct inclusion means, for me, that I should include asm/spinlock.h, because of all that I need only arch_spin_lock() and arch_spin_unlock(). Am I wrong? Yury

qrwlock.c calls arch_spin_lock() and arch_spin_unlock() but doesn't include the asm/spinlock.h, where those functions are defined. It may produce "implicit declaration of function" errors. This patch fixes it. Signed-off-by: Yury Norov <ynorov@caviumnetworks.com> --- kernel/locking/qrwlock.c | 1 + 1 file changed, 1 insertion(+) -- 2.11.0
