julian 1999/10/31 20:57:44 PST Modified files: sys/kern vfs_syscalls.c sys/sys mount.h bin/df df.1 df.c Log: Most modern OSs have the ability to flag certain mounts as ones to be ignored by default by the df(1) program. This is used mostly to avoid stat()-ing entries that do not represent "real" disk mount points (such as those made by an automounter such as amd.) It is also useful not to have to stat() these entries because it takes longer to report them that for other file systems, being that these mount points are served by a user-level file server and resulting in several context switches. Worse, if the automounter is down unexpectedly, a causal df(1) will hang in an interruptible way.
