Subject: linux-user: fix mismatch of lock/unlock_user() invocations in rt_sigqueinfo() syscall
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d8b6d892c66c1b6f505cd5a2576e08deea200e6d;p=qemu.git

linux-user: fix mismatch of lock/unlock_user() invocations in rt_sigqueinfo() syscall

Change the unlock_user() argument from arg1 to arg3 to match with
lock_user(), since arg3 contains the pointer to the siginfo_t structure.
