Modified files:
sys/kern syscalls.master
sys/sys sysproto.h umtx.h
Log:
The undocumented and deprecated system call _umtx_op() takes two pointer
arguments. The first one is never used (all callers pass in 0); the
second is sometimes used to pass in a struct timespec * which is used as
a timeout and never modified. Constify that argument so callers can pass
a const struct timespec * without jumping through hoops.
Revision Changes Path
1.214 +1 -1 src/sys/kern/syscalls.master
1.193 +1 -1 src/sys/sys/sysproto.h
1.18 +3 -3 src/sys/sys/umtx.h
This is an incorrect change, please backout it. the _umtx_op parameters
never should only accept const void *, in fact, the interface was
designed to extendable for future use. you can use __DECONST macro in
umtx.h to disable compiler warnings, breaking it could cause FreeBSD to
not have optimized thread library can be used.next when you want to
change umtx code, please discuss with me first.
