H A Dreservations.hdiff e3b4a97dbe9741a3227c3ed857a0632532fcd386 Mon Dec 07 15:16:07 CST 2009 Mark Fasheh <mfasheh@suse.com> ocfs2: use allocation reservations for directory data

Use the reservations system for unindexed dir tree allocations. We don't
bother with the indexed tree as reads from it are mostly random anyway.
Directory reservations are marked seperately, to allow the reservations code
a chance to optimize their window sizes. This patch allocates only 8 bits
for directory windows as they generally are not expected to grow as quickly
as file data. Future improvements to dir window sizing can trivially be
made.
