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.

fs_cachep is only used in kernel/exit.c and in kernel/fork.c.
It is used to store fs_struct items so it should be placed in linux/fs_struct.h

It's only need for the two monster-inlines set_fs_root and set_fs_pwd
that should better be out of line anyway. Some additional cleanup like
named initializers as extra bonus.

OK, here comes. Patch below is an attempt to do the fastwalk
stuff in right way and so far it seems to be working.
- dentry leak is plugged
- locked/unlocked state of nameidata doesn't depend on history - it
depends only on point in code.
- LOOKUP_LOCKED is gone.
- following mounts and .. doesn't drop dcache_lock
- light-weight permission check distinguishes between "don't know" and
"permission denied", so we don't call full-blown permission() unless
we have to.
- code that changes root/pwd holds dcache_lock _and_ write lock on
current->fs->lock. I.e. if we hold dcache_lock we can safely
access our ->fs->{root,pwd}{,mnt}
- __d_lookup() does not increment refcount; callers do dget_locked()
if they need it (behaviour of d_lookup() didn't change, obviously).
- link_path_walk() logics had been (somewhat) cleaned up.

Big bits first, I'll redo the smaller bits tomorrow after some sleep.
Same as last time, rediffed against pre5

- Andreas Dilger: various ext2 cleanups
- Richard Gooch: devfs update
- Johannes Erdfelt: USB updates
- Alan Cox: merges
- David Miller: fix SMP pktsched bootup deadlock (CONFIG_NET_SCHED)
- Roman Zippel: AFFS update
- Anton Altaparmakov: NTFS update
- me: fix races in vfork() (semaphores are not good completion handlers)
- Jeff Garzik: net driver updates, sysvfs update
|
|
- Rik van Riel and others: mm rw-semaphore (ps/top ok when swapping)
- IDE: 256 sectors at a time is legal, but apparently confuses some
drives. Max out at 255 sectors instead.
- Petko Manolov: USB pegasus driver update
- make the boottime memory map printout at least almost readable.
- USB driver updates
- pte_alloc()/pmd_alloc() need page_table_lock.
