| H A D | vfs_cache.c | diff 144318 Wed Mar 30 00:59:32 MST 2005 das Merge kern___cwd() and vn_fullpath(), which were virtually identical, except for places where people forget to update one of them. We now collect only one set of stats for both of these routines. Other changes in this commit include: - Start acquiring Giant again in vn_fullpath(), since it is required when crossing a mount point. - Expand the scope of the cache lock to avoid dropping it and picking it up again for every pathname component. This also makes it trivial to avoid races in stats collection. - Assert that nc_dvp == v_dd for directories instead of returning an error to userland when this is not true. AFAIK, it should always be true when v_dd is non-null. - For vn_fullpath(), handle the first (non-directory) vnode separately. Glanced at by: jeff, phk |
