| 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. |
