Hi, everybody<= /DIV>

I am working on transfer RaidFrame from FreeBSD4.x to Fr= eeBSD5.0. Scott Long has transfered RAIDFrame from NetBSD to FreeBS= D 4.x.

Now, I am transfering those codes to FreeBSD5.0. This i= s my first strolling in FreeBSD5.0 kernel.

Firstly, I t= ransfered some codes based on the relationship of vinum and ccd between 4= .x and 5.0. It could compile successfully.

Now when I bo= ot the box, the system tell me:

panic: sleeping without = a mutex

Debugger("panic")

Stopped at Debugger= +0x40: xorl %eax,%eax

I traced the source co= de and found some information as follow:

These is a function o= n RAIDFrame in the FreeBSD4.x .

static __inline int
RF_LTSL= EEP(void *cond, int pri, const char *text, int time, struct simplelock *m= utex)
{
int ret;
if (mutex !=3D NULL)
= ;simple_unlock(mutex);
ret =3D tsleep(cond, pri, text, time); if (mutex !=3D NULL)
simple_lock(mutex);
r= eturn (ret);
}

These is the above funtion I modifed to = support FreeBSD5.0:

static __inline int
RF_LTSLEEP(void *co= nd, int pri, const char *text, int time, struct mtx *mutex)
{
= ;int ret;
if (mutex !=3D NULL)
mtx_unlock(mutex);=
ret =3D tsleep(cond, pri, text, time);
if (mutex !=3D = NULL)
mtx_lock(mutex);
return (ret);
}

<= DIV>

I have a clear ideal to use mtx.

I thin= k there are maybe some problem in using the mtx.

Thank you ver= y much!

Best Regards
Ouyang Kai
