 hello everyone,

 i think there's a bug in 2.2.13 kernel that causes it to OOPS when
 fchown()ing a socket - this is what i get when trying to do so:

Unable to handle kernel NULL pointer dereference at virtual address 0000001c
current->tss.cr3 = 01707000, %cr3 = 01707000
*pde = 01709067
*pte = 00000000

 or maybe i'm missing something?

    thanks in advance,
