| | | | | | | | | | | | | | | | | | systems were repo-copied from sys/miscfs to sys/fs. - Renamed the following file systems and their modules: fdesc -> fdescfs, portal -> portalfs, union -> unionfs. - Renamed corresponding kernel options: FDESC -> FDESCFS, PORTAL -> PORTALFS, UNION -> UNIONFS. - Install header files for the above file systems. - Removed bogus -I${.CURDIR}/../../sys CFLAGS from userland Makefiles.

| | | | | | | | | | | | | | | | | | what is teh root cause -- but, sometimes, a procfs vnode in pfshead is apparantly corrupt (or a UFS vnode instead). Without this patch, I can get it to panic by doing (in csh) while (1) ps auxwww end and it will panic when the PID's wrap. With it, it does not panic. Yes -- I know that this is NOT the right way to fix it. But I haven't been able to get it to panic yet (which confuses me). I am going to be looking into the vgone() code now, as that may be a part of it. Notes: svn path=/head/; revision=31640
* Use at_exit() to invoke procfs_exit() instead of calling it directly.Sean Eric Fagan1997-12-081-2/+3
| | | | | | | | | | | Note that an unload facility should be used to call rm_at_exit() (if procfs is being loaded as an LKM and is subsequently removed), but it was non-obvious how to do this in the VFS framework. Reviewed by: Julian Elischer Notes: svn path=/head/; revision=31618
