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  provide  a
     fallback vnode operations vector for reclaimed vnode(9)'s.

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

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)
