I discovered on oprofile hunting on a SMP platform that dentry lookups were
slowed down because d_hash_mask, d_hash_shift and dentry_hashtable were in
a cache line that contained inodes_stat. So each time inodes_stats is
changed by a cpu, other cpus have to refill their cache line.This patch moves some variables to the __read_mostly section, in order to
avoid false sharing. RCU dentry lookups can go full speed.Signed-off-by: Eric Dumazet

Semaphore to mutex conversion.
The conversion was generated via scripts, and the result was validated
automatically via a script as well.Signed-off-by: Ingo Molnar

Dcookies shouldn't play with the internals of dentry and vfsmnt
refcounting. It defeats grepping, and is prone to break if implementation
details change.In addition the function doesn't even seem to be performance critical: it
calls kmem_cache_alloc().Signed-off-by: Miklos Szeredi

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!
