hi

i'm trying to write a block allocator which gonna co-exists with the
ext2fs module.
my question is how can i  lock the super_block to avoid conflicits on
SMP machines ?

i saw that the lock_kernel function recieve a pointer to the super_block
struct, so i guess it must point to the same struct which the ext2fs
module is holding.

how can i get a referance to it ? it looks like the read_super and the
ext2fs_open both read the data from the disk into a newly allocated
struct.

/gabriel

please CC me for  any answer as i'm not register to the mailing list
