truckman 2004/03/05 14:03:11 PST FreeBSD src repository Modified files: sys/kern kern_sysctl.c sys/vm vm_extern.h vm_glue.c vm_mmap.c Log: Undo the merger of mlock()/vslock and munlock()/vsunlock() and the introduction of kern_mlock() and kern_munlock() in src/sys/kern/kern_sysctl.c 1.150 src/sys/vm/vm_extern.h 1.69 src/sys/vm/vm_glue.c 1.190 src/sys/vm/vm_mmap.c 1.179 because different resource limits are appropriate for transient and "permanent" page wiring requests. Retain the kern_mlock() and kern_munlock() API in the revived vslock() and vsunlock() functions. Combine the best parts of each of the original sets of implementations with further code cleanup. Make the mclock() and vslock() implementations as similar as possible. Retain the RLIMIT_MEMLOCK check in mlock(). Move the most strigent test, which can return EAGAIN, last so that requests that have no hope of ever being satisfied will not be retried unnecessarily. Disable the test that can return EAGAIN in the vslock() implementation because it will cause the sysctl code to wedge.
