vfs_create() ignores everything outside of 16bit subset of its

vfs_mkdir() gets int, but immediately drops everything that might not
fit into umode_t and that's the only caller of ->mkdir()...Signed-off-by: Al Viro

Only a few file systems need this. Start by pushing it down into each
rename method (except gfs2 and xfs) so that it can be dealt with on a

Reduce some branches and memory accesses in dcache lookup by adding dentry
flags to indicate common d_ops are set, rather than having to check them.
This saves a pointer memory access (dentry->d_op) in common path lookup
situations, and saves another pointer load and branch in cases where we
have d_op but not the particular operation.Patched with:
git grep -E '[.>]([[:space:]])*d_op([[:space:]])*=' | xargs sed -e 's/\([^\t ]*\)->d_op = \(.*\);/d_set_d_op(\1, \2);/' -e 's/\([^\t ]*\)\.d_op = \(.*\);/d_set_d_op(\&\1, \2);/' -i

Change d_hash so it may be called from lock-free RCU lookups. See similar
patch for d_compare for details.For in-tree filesystems, this is just a mechanical change.

Change d_compare so it may be called from lock-free RCU lookups. This
does put significant restrictions on what may be done from the callback,
however there don't seem to have been any problems with in-tree fses.
If some strange use case pops up that _really_ cannot cope with the
rcu-walk rules, we can just add new rcu-unaware callbacks, which would
cause name lookup to drop out of rcu-walk mode.For in-tree filesystems, this is just a mechanical change.

Use ERR_CAST(x) rather than ERR_PTR(PTR_ERR(x)). The former makes more
clear what is the purpose of the operation, which otherwise looks like a
no-op.The semantic patch that makes this change is as follows:

type T;
T x;
identifier f;
@@T f (...) { }

- remove affs_put_inode, so preallocations aren't discared unnecessarily
often.
- remove affs_drop_inode, it's called with a spinlock held, so it can't
use a mutex.
- make i_opencnt atomic
- avoid direct b_count manipulations
- a few allocation failure fixes, so that these are more gracefully
handled now.

Stop the AFFS filesystem from using iget() and read_inode(). Replace
affs_read_inode() with affs_iget(), and call that instead of iget().
affs_iget() then uses iget_locked() directly and returns a proper error code
instead of an inode in the event of an error.affs_fill_super() returns any error incurred when getting the root inode
instead of EINVAL.[akpm@linux-foundation.org: coding-style fixes]

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!
