make ntfs_ntref() real function and properly lock ip->i_interlock when
updating ip->i_usecount
g/c ntfs_uustricmp()
make ntfs_uastr[i]cmp() static, rename arguments to be a bit more mnemonic
add couple of casts to NTFS_TOUPPER() and ntfs_uastr[i]cmp() - this
corrects couple of cases when open()/stat() failed for
files which apparently existed and even showed in ls output
ntfs_ntlookup(): initialize ip properly if ntnode is found in hash table,
so that debug prints doesn't print garbage in that case
some whitespace policy
