sys/param.h was manually adjusted to not define __NetBSD_Version__ since it will be defined by the compiler.

/*
|
|
* This macro provides an initializer list for the fs-independent part
|
|
* of a filesystem's fifo vnode ops descriptor table. We still need
|
|
* such a table in every filesystem, but we can at least avoid the
|
|
* cutpaste.
|
|
*
|
|
* This contains these ops:
|
|
* parsepath lookup
|
|
* create whiteout mknod open fallocate fdiscard ioctl poll kqfilter
|
|
* revoke mmap seek remove link rename mkdir rmdir symlink readdir
|
|
* readlink abortop bmap pathconf advlock getpages putpages
|
|
*
|
|
* The filesystem should provide these ops that need to be its own:
|
|
* access and accessx
|
|
* getattr
|
|
* setattr
|
|
* fcntl
|
|
* inactive
|
|
* reclaim
|
|
* lock
|
|
* unlock
|
|
* strategy
|
|
* print (should probably also call fifo_print)
|
|
* islocked
|
|
* bwrite (normally vn_bwrite)
|
|
* openextattr
|
|
* closeextattr
|
|
* getextattr
|
|
* setextattr
|
|
* listextattr
|
|
* deleteextattr
|
|
* getacl
|
|
* setacl
|
|
* aclcheck
|
|
*
|
|
* The filesystem should also provide these ops that some filesystems
|
|
* do their own things with:
|
|
* close
|
|
* read
|
|
* write
|
|
* fsync
|
|
* In most cases "their own things" means adjust timestamps and call
|
|
* fifo_foo (currently via vn_fifo_bypass). For fsync it varies.
|
|
*
|
|
* Note that because the op descriptor tables are unordered it does not
|
|
* matter where in the table this macro goes (except I think default
|
|
* still needs to be first...)
|
|
*
|
|
* XXX currently all the ops are vn_fifo_bypass, which does an
|
|
* indirect call via the fifofs ops table (externed above), which
|
|
* someone decided was preferable to exposing the function
|
|
* definitions. This includes (for now at least) the ones that are
|
|
* sent to genfs by that table. This should probably be changed, but
|
|
* not just yet.
