of stat(2) calls by keeping an eye of the number of links a directory has. It assumes that each subdirectory will have a hard link to its parent, to represent the ".." node, and stops calling stat(2) when all links are accounted for in a given directory. This assumption is really only valid for UNIX-like filesystems: A concrete example is NTFS. The NTFS "i-node" does contain a link count, but most/all directories have a link count between 0 and 2 inclusive. The end result is that find on an NTFS volume won't actually traverse the entire hierarchy of the directories passed to it. (Those with a link count of two are not traversed at all) The fix checks the "UFSness" of the filesystem before enabling the optimisation. Reviewed By: Tim Kientzle (kientzle@) |
