fuse: fix permission checking

2008-02-24T01:12:13+00:00

I added a nasty local variable shadowing bug to fuse in 2.6.24, with the
result, that the 'default_permissions' mount option is basically ignored.

How did this happen?

 - old err declaration in inner scope
 - new err getting declared in outer scope
 - 'return err' from inner scope getting removed
 - old declaration not being noticed

-Wshadow would have saved us, but it doesn't seem practical for
the kernel :(

More testing would have also saved us :((

fuse: limit queued background requests

2008-02-06T18:41:13+00:00

Libfuse basically creates a new thread for each new request.  This is fine for
synchronous requests, which are naturally limited.  However background
requests (especially writepage) can cause a thread creation storm.

To avoid this, limit the number of background requests available to userspace.

This is done by introducing another queue for background requests, and a
counter for the number of "active" requests, which are currently available for
userspace.

fuse: save space in struct fuse_req

Move the fields 'dentry' and 'vfsmount' into the request specific union, since
these are only used for the RELEASE request.

Kobject: convert fs/* from kobject_unregister() to kobject_put()

2008-01-25T04:40:40+00:00

There is no need for kobject_unregister() anymore, thanks to Kay's
kobject cleanup changes, so replace all instances of it with
kobject_put().

kobject: convert main fs kobject to use kobject_create

2008-01-25T04:40:13+00:00

This also renames fs_subsys to fs_kobj to catch all current users with a
build error instead of a build warning which can easily be missed.

kobject: convert fuse to use kobject_create

2008-01-25T04:40:11+00:00

We don't need a kset here, a simple kobject will do just fine, so
dynamically create the kobject and use it.
