NAME
mptctl_syscall_down - Down the MPT adapter syscall semaphore.
SYNOPSIS
int mptctl_syscall_down(MPT_ADAPTER * ioc, int nonblock);
ARGUMENTS
ioc Pointer to MPT adapter nonblock boolean, non-zero if O_NONBLOCK is set
DESCRIPTION
All of the ioctl commands can potentially sleep, which is illegal with a spinlock held, thus we perform mutual exclusion here. Returns negative errno on error, or zero for success.
