The rs_requested field is left over from the original allocation code, however this should have been a parameter passed to the various functions from gfs2_inplace_reserve() and not a member of the reservation structure as the value is not required after the initial allocation. This also helps simplify the code since we no longer need to set the rs_requested to zero. Also the gfs2_inplace_release() function can also be simplified since the reservation structure will always be defined when it is called, and the only remaining task is to unlock the rgrp if required. It can also now be called unconditionally too, resulting in a further simplification. Signed-off-by: Steven Whitehouse <swhiteho@redhat.com>
