falloc()

[Yan Yu]

Hi, all,
  I am wondering if there is a way to use kernel loadable module to
replace the original falloc() (kern/kern_descrip.c) in the system.
I know how to do this if the funciton to be replaced is some system call
function or ufs* operatio ( i could just change the symbol table which
holds these function pointers),.
but i could not find the symbol table which holds the falloc() function
pointer...

Any pointers are appreciated!
