[PATCH] do shrink_submounts() for all fs types

2008-03-28T00:47:58+00:00

... and take it out of ->umount_begin() instances.  Call with all locks
already taken (by do_umount()) and leave calling release_mounts() to
caller (it will do release_mounts() anyway, so we can just put into
the same list).

[PATCH] sanitize locking in mark_mounts_for_expiry() and shrink_submounts()

2008-03-28T00:47:52+00:00

... and fix a race on access of ->mnt_share et.al. without namespace_sem
in the latter.

[PATCH] count ghost references to vfsmounts

2008-03-28T00:47:46+00:00

make propagate_mount_busy() exclude references from the vfsmounts
that had been isolated by umount_tree() and are just waiting for
release_mounts() to dispose of their ->mnt_parent/->mnt_mountpoint.

[PATCH] reduce stack footprint in namespace.c

2008-03-28T00:47:40+00:00

A lot of places misuse struct nameidata when they need struct path.

d_path: Make seq_path() use a struct path argument

2008-02-15T05:17:08+00:00

seq_path() is always called with a dentry and a vfsmount from a struct path.
Make seq_path() take it directly as an argument.

Make set_fs_{root,pwd} take a struct path

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

In nearly all cases the set_fs_{root,pwd}() calls work on a struct
path. Change the function to reflect this and use path_get() here.

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.
