DEADFS(9)		   Kernel Developer's Manual		     DEADFS(9)

NAME
       deadfs -- pseudo-filesystem to own reclaimed vnodes

DESCRIPTION
       The  deadfs  file  system  implements operations	that do	not modify any
       data and	instead	return indications of invalid IO.  Its role is to pro-
       vide a fallback vnode operations	vector for reclaimed vnode(9)'s.

       It is a kernel-only pseudo-file system and so cannot  be	 mounted  from
       userspace.

SEE ALSO
       insmntque(9), vnode(9), VOP_RECLAIM(9)

HISTORY
       UNIX  System  Manager's	Manual	(SMM) for 4.4BSD described deadfs as a
       file system "where rejected vnods go to die".

AUTHORS
       The  deadfs   manual   page   was   written   by	  Mateusz   Piotrowski
       <0mp@FreeBSD.org>.

FreeBSD	ports 15.quarterly     October 24, 2025			     DEADFS(9)
