The docID is the pair (filesystemID, inode_number) where filesystemID := I(mount_point(filepath)). M is only introduced to make determining mount_point(filepath) more efficient by using cached values M(stat.st_dev(filepath)). The number of cache entries never exceeds the number of mounted filesystems. > and when searching (going from the docID > to the canonical filename). To get from docID to the filepath, without storing the filepath, one can maintain a reverse map of I to get the mount point for a given internal filesystem ID. Once one has the mount point, one can get the current stat.st_dev for the filesystem which is currently used to get the filepath for a given inode_number. I am suggesting this alternative as the current proposal requires filesystem-specific code such as looking for the special string "subvolid" in findmnt output. Another filesystem may call it something else. One doesn't want to write code for each possible filesystem and update it each time somebody publishes a new filesystem. -- You are receiving this mail because: You are watching all bug changes.
