ocfs2: make ocfs2_adjust_resv_from_alloc simple.
When we allocate some bits from the reservation, we always
allocate from the r_start(see ocfs2_resmap_resv_bits).
So there should be no reason to check between r_start
and start. And I don't think we will change this behaviour
later by allocating from some bits after r_start. Why not make
ocfs2_adjust_resv_from_alloc simple for now?
The only chance we have to adjust the reservation is when we haven't
reached the end. With this patch, the function is more readable.
Note:
btw, this patch also fixes an original bug in the function
which I haven't found before.
if (end < ocfs2_resv_end(resv))
rhs = end - ocfs2_resv_end(resv);
This code is of course buggy. ;)
