open-style analog of vfs_path_lookup()

2011-03-14T13:15:28+00:00

new function: file_open_root(dentry, mnt, name, flags) opens the file
vfs_path_lookup would arrive to.

Note that name can be empty; in that case the usual requirement that
dentry should be a directory is lifted.

open-coded equivalents switched to it, may_open() got down exactly
one caller and became static.

vfs: nfsctl.c un-used nfsd #includes

2009-12-14T23:12:11+00:00

Only linux/nfsd/syscall.h is actually used. Remove the
other nfsd #includes, so they can be moved to source
directory.

pass a struct path * to may_open

2008-12-31T23:07:41+00:00

No need for the nameidata in may_open - a struct path is enough.

nfsctl: add headers for credentials

2008-11-19T21:11:55+00:00

Needs headers help for current_cred:

Adding only cred.h wasn't enough.

CRED: Pass credentials through dentry_open()

2008-11-13T23:39:22+00:00

Pass credentials through dentry_open() so that the COW creds patch can have
SELinux's flush_unauthorized_files() pass the appropriate creds back to itself
when it opens its null chardev.

The security_dentry_open() call also now takes a creds pointer, as does the
dentry_open hook in struct security_operations.

Introduce path_put()

2008-02-15T05:13:33+00:00

* Add path_put() functions for releasing a reference to the dentry and
  vfsmount of a struct path in the right order

* Switch from path_release(nd) to path_put(&nd->path)

* Rename dput_path() to path_put_conditional()

Embed a struct path into struct nameidata instead of nd->{dentry,mnt}

2008-02-15T05:13:33+00:00

This is the central patch of a cleanup series. In most cases there is no good
reason why someone would want to use a dentry for itself. This series reflects
that fact and embeds a struct path into nameidata.

Together with the other patches of this series
- it enforced the correct order of getting/releasing the reference count on
   pairs
- it prepares the VFS for stacking support since it is essential to have a
  struct path in every place where the stack can be traversed
- it reduces the overall code size:

without patch series:
   text    data     bss     dec     hex filename
5321639  858418  715768 6895825  6938d1 vmlinux

with patch series:
   text    data     bss     dec     hex filename
5320026  858418  715768 6894212  693284 vmlinux

This patch:

Switch from nd->{dentry,mnt} to nd->path.{dentry,mnt} everywhere.
