Joel Becker eed7a0db46 configfs: configfs_mkdir() failed to cleanup linkage.
If configfs_mkdir() errored in certain ways after the parent<->child
linkage was already created, it would not undo the linkage.  Also,
comment the reference counting for clarity.

Joel Becker 84efad1a53 configfs: Fix a reference leak in configfs_mkdir().
configfs_mkdir() failed to release the working parent reference in most
exit paths.  Also changed the exit path for readability.

Eric Sesterhenn cbca692c24 [PATCH] Bogus NULL pointer check in fs/configfs/dir.c
We check the "group" pointer after we dereference it.  This check is
bogus, as it cannot be NULL coming in.

Arjan van de Ven 4b6f5d20b0 [PATCH] Make most file operations structs in fs/ const
This is a conversion to make the various file_operations structs in fs/
const.  Basically a regexp job, with a few manual fixups

The goal is both to increase correctness (harder to accidentally write to
shared datastructures) and reducing the false sharing of cachelines with
things that get dirty in .data (while .rodata is nicely read only and thus
cache clean)

Joel Becker 3d0f89bb16 configfs: Add permission and ownership to configfs objects.
configfs always made item and attribute ownership root.root and
permissions based on a umask of 022.  Add ->setattr() to allow
chown(2)/chmod(2), and persist the changes for the lifetime of the
items and attributes.

Jes Sorensen 1b1dcc1b57 [PATCH] mutex subsystem, semaphore to mutex: VFS, ->i_sem
This patch converts the inode semaphore to a mutex. I have tested it on
XFS and compiled as much as one can consider on an ia64. Anyway your
luck with it might be different.

Joel Becker 7063fbf226 [PATCH] configfs: User-driven configuration filesystem
Configfs, a file system for userspace-driven kernel object configuration.

configuration information into kernel.
