Hi, everybody
I am working on transfer RaidFrame from FreeBSD4.x to FreeBSD5.0. Scott=
Long has transfered RAIDFrame from NetBSD to FreeBSD 4.x.
Now, I am transfering those codes to FreeBSD5.0. This is my first strolli=
ng in FreeBSD5.0 kernel. =20
Firstly, I transfered some codes based on the relationship of vinum and =
ccd between 4.x and 5.0. It could compile successfully.
Now when I boot the box, the system tell me:
panic: sleeping without a mutex
Debugger("panic")
Stopped at Debugger+0x40: xorl %eax,%eax
I traced the source code and found some information as follow:
These is a function on RAIDFrame in the FreeBSD4.x .
static __inline int
RF_LTSLEEP(void *cond, int pri, const char *text, int time, struct simple=
lock *mutex)
{
int ret;
if (mutex !=3D NULL)
simple_unlock(mutex);
ret =3D tsleep(cond, pri, text, time);
if (mutex !=3D NULL)
simple_lock(mutex);
return (ret);
}
These is the above funtion I modifed to support FreeBSD5.0:
static __inline int
RF_LTSLEEP(void *cond, int pri, const char *text, int time, struct mtx *m=
utex)
{
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);
}
I have a clear ideal to use mtx. =20
I think there are maybe some problem in using the mtx.
Thank you very much!
Best Regards
