boolean "does it have to be exclusive?" flag is passed instead;
Local filesystem should just ignore it - the object is guaranteed
not to be there yet.

Just the flags; only NFS cares even about that, but there are
legitimate uses for such argument.  And getting rid of that
completely would require splitting -&gt;lookup() into a couple
of methods (at least), so let's leave that alone for now...

<title>vfs: make it possible to access the dentry hash/len as one 64-bit entry</title>

This allows comparing hash and len in one operation on 64-bit
architectures.  Right now only __d_lookup_rcu() takes advantage of this,
since that is the case we care most about.

The use of anonymous struct/unions hides the alternate 64-bit approach
from most users, the exception being a few cases where we initialize a
'struct qstr' with a static initializer.  This makes the problematic
cases use a new QSTR_INIT() helper function for that (but initializing
just the name pointer with a "{ .name = xyzzy }" initializer remains
valid, as does just copying another qstr structure).

New field of struct super_block - -&gt;s_max_links.  Maximal allowed
value of -&gt;i_nlink or 0; in the latter case all checks still need
to be done in -&gt;link/-&gt;mkdir/-&gt;rename instances.  Note that this
limit applies both to directoris and to non-directories.

vfs_create() ignores everything outside of 16bit subset of its
mode argument; switching it to umode_t is obviously equivalent
and it's the only caller of the method

Replace the -&gt;check_acl method with a -&gt;get_acl method that simply reads an
ACL from disk after having a cache miss.  This means we can replace the ACL
checking boilerplate code with a single implementation in namei.c.
