| |
Hi Peter,
your commit f233f7f1581e ("locking/pvqspinlock, x86: Implement the paravirt qspinlock call patching") is in today's linux-next tree (i.e., next-20150511). The two #ifdef blocks listed below cannot be compiled at the current state since CONFIG_QUEUED_SPINLOCKS does not exist:
+#if defined(CONFIG_PARAVIRT_SPINLOCKS) && defined(CONFIG_QUEUED_SPINLOCKS) [...] +#if defined(CONFIG_PARAVIRT_SPINLOCKS) && defined(CONFIG_QUEUED_SPINLOCKS)
It seems that it's just a typo, since QUEUED_SPINLOCK (i.e., without last S) is defined in kernel/Kconfig.locks.
I detected this issue with scripts/checkkconfigsymbols.py by diffing today's and the previous next tree.
Kind regards, Valentin
