Hello,

1)

I am modifying the mount code and i find this: malloc(...,M_UFSMNT,...)

In malloc.h:
#define M_UFSMNT 28

There is a lot of "define" about filesystems in malloc.h and it seems to represent every types of memories which can be allocated. I'm searching in the source but i don't know how and why they use it. Someone knows the solution?
What does represent a type of memory?

2)

Does someone knows the working of the bread function because it returns me the EINVAL error. Does it read a logical block or a physical block? I'm trying to read my disk superblock, my creds, vnode and offset seem to be correct but i don't know where is the error and i have no idea about it.

Thanks. Received on Sun Aug 3 16:28:10 2003
