SubjectRe: ext2fs enhacement/fix [re: shrinking directories]
How about a simple utility, added to the ext2 utilities, that compacts
directories that can be run periodically as the user wishes. By the way
don't these ghost entries hamper performance, albeit possibly by a
negligible amount. I would think that these ghost entries get processed
along with the other entries whenever the directory is accessed. And if
this utility is made other file system optimization options can be thrown
in. Perhaps the directory entries can be sorted by their last access date
as the directory is compacted so as to improve file access performance.
