/*
* HISTORY
* $Log: stat.h,v $
* 7-Jan-93 Mac Gillon (mgillon) at NeXT
* Integrated POSIX support
*
* 22-Feb-90 Gregg Kellogg (gk) at NeXT
* Added back in STAT_BSIZE, STAT_BSHIFT, btosb, and sbtob
*
* Revision 2.5 89/04/22 15:32:24 gm0w
* Removed MACH_VFS changes.
* [89/04/14 gm0w]
*
* Revision 2.4 89/03/09 22:07:51 rpd
* More cleanup.
*
* Revision 2.3 89/02/25 17:56:28 gm0w
* Made items previously conditional on CMUCS and MACH_VFS
* be unconditional.
* [89/02/14 mrt]
*
* Revision 2.2 89/01/18 01:19:13 jsb
* Vnode support: define S_IFIFO.
* [89/01/13 jsb]
*
* 06-Jan-88 Jay Kistler (jjk) at Carnegie Mellon University
* Made file reentrant. Added declarations for __STDC__.
*
* 11-Aug-87 Peter King (king) at NeXT
* SUN_VFS: Added S_IFIFO for nfs routines (nfs_subr.c)
*
* 11-Dec-86 Jonathan J. Chew (jjc) at Carnegie-Mellon University
* Added a variation of the stat structure that explicitly puts
* in padding where the Vax and RT compilers implicitly put it.
* This is for the Sun which does not align long fields on a long
* boundary.
*
* 25-Jan-86 Avadis Tevanian (avie) at Carnegie-Mellon University
* Upgraded to 4.3.
