| H A D | ufs_dirhash.c | diff 79690 Fri Jul 13 18:50:38 MDT 2001 iedowse Return a locked struct buf from ufsdirhash_lookup() to avoid one extra getblk/brelse sequence for each lookup. We already had this buf in ufsdirhash_lookup(), so there was no point in brelse'ing it only to have the caller immediately reaquire the same buffer. This should make the case of sequential lookups marginally faster; in my tests, sequential lookups with dirhash enabled are now only around 1% slower than without dirhash. |
