When calling sysfs_remove_dir() don't allow any further sysfs functions
to work for this kobject anymore. This fixes a nasty USB cdc-acm oops
on disconnect.
Many thanks to Bob Copeland and Paul Fulghum for taking the time to
track this down.

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.

I noticed that if sysfs_make_dirent fails to allocate the sd, then a
null will be passed to sysfs_put.

Various filesystem drivers have grown a get_dentry() function that's a
duplicate of lookup_one_len, except that it doesn't take a maximum length
argument and doesn't check for \0 or / in the passed in filename.
Switch all these places to use lookup_one_len.

o This adds ->i_op->setattr VFS method for sysfs inodes. The changed
attribues are saved in the persistent sysfs_dirent structure as a pointer
to struct iattr. The struct iattr is allocated only for those sysfs_dirent's
for which default attributes are getting changed. Thanks to Jon Smirl for
this suggestion.

o The following patch makes sure to attach sysfs_dirent to the dentry before
allocation a new inode through sysfs_create(). This change is done as
preparatory work for implementing ->i_op->setattr() functionality for
sysfs objects.

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
