Subject[PATCH] locking/Kconfig: Don't forcefully uninline spin_unlock for PREEMPT
Date
From: Sultan Alsawaf <sultan@kerneltoast.com>

This change was originally done in 2005 without any justification in
commit bda98685b855 ("[PATCH] x86: inline spin_unlock if
!CONFIG_DEBUG_SPINLOCK and !CONFIG_PREEMPT"). Perhaps the reasoning at
the time was that PREEMPT was still considered unstable and needed extra
debugging; however, this is no longer the case, so remove the artificial
limitation.

This option reduces the latency of the kernel by making
all kernel code (that is not executing in a critical section)
