From 52942c1eae52930adaa4f1204cde66add18547fe Mon Sep 17 00:00:00 2001 From: Ed Schouten Date: Mon, 3 Aug 2015 21:11:33 +0000 Subject: [PATCH] Add missing const keyword to function parameter. The umtx_key_get() function does not dereference the address off the userspace object. The pointer can safely be const. --- sys/kern/kern_umtx.c | 2 +- sys/sys/umtx.h | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/sys/kern/kern_umtx.c b/sys/kern/kern_umtx.c index 8ff8f764dedb..cf472912164b 100644 --- a/sys/kern/kern_umtx.c +++ b/sys/kern/kern_umtx.c @@ -793,7 +793,7 @@ umtxq_sleep(struct umtx_q *uq, const char *wmesg, struct abs_timeout *abstime) * Convert userspace address into unique logical address. */ int -umtx_key_get(void *addr, int type, int share, struct umtx_key *key) +umtx_key_get(const void *addr, int type, int share, struct umtx_key *key) { struct thread *td = curthread; vm_map_t map; diff --git a/sys/sys/umtx.h b/sys/sys/umtx.h index 07794dfe038b..145950710a10 100644 --- a/sys/sys/umtx.h +++ b/sys/sys/umtx.h @@ -153,7 +153,7 @@ umtx_key_match(const struct umtx_key *k1, const struct umtx_key *k2) } int umtx_copyin_timeout(const void *, struct timespec *); -int umtx_key_get(void *, int, int, struct umtx_key *); +int umtx_key_get(const void *, int, int, struct umtx_key *); void umtx_key_release(struct umtx_key *); struct umtx_q *umtxq_alloc(void); void umtxq_free(struct umtx_q *);
