ntfs_findvattr(), AALPCMP --> NTFS_AALPCMP, avoid excessive
intendation, fix debug printf when the attribute is not found
to print only first namelen characters of name
some minor KNF and const poisoning
ntfs_ntlookupattr(): make it static, collapse duplicated code
ntfs_ntlookupfile(): avoid memory leak, explicitly set error to 0 when
returning success
kill some bogus comments
changes: cache_lookup() now returns -1 if not successful; for
the '.' case, 'error' haven't been cleared to 0,
so that ntfs_lookup() itself returned -1 , resulting to
nasty "leaf should be empty" panic early after
routines - avoids potential DoS attack and closes an easy way to force
the kernel to panic
* for read(), DTRT WRT offset bigger than file size
ntfs_strategy(): adapt to ntfs_readattr() change
ntfs_readdir(): use ntfs_u28() to translate the file name characters
to 8bit encoding, avoid excessive intendation, reformat the
debug messages slightly
uio parameter; if it's not null, the data are copied directly
into/from the user buffer via uiomove()
new macro NTFS_U28() and function ntfs_u28() to convert between Unicode
and 8bit encoding; all it does currently is getting lower 8bit
of the Unicode char and subtituting '_' for it if the result would be 0;
use the macro within NTFS_TOUPPER() macro and in ntfs_uastrcmp()
g/c the (ntfsmount *) parametr to ntfs_u*astr[i]cmp() functions, it's no
longer needed
avoid excessive intendation
is mounted and all ntfs volumes share it; the space occupied by the
table is freed upon last ntfs volumen umount. Saves 128KB for every
ntfs volume mounted.
XXX for now, read just first 256 entries - no more would be currently used
anyway
* return EROFS for volume mounted RO when the nameiop is DELETE or RENAME
(the same way ufs_lookup() does)
* add explicit call to cache_lookup() on NetBSD (handled by generic VFS
layer in FreeBSD)
* avoid using strncmp() when checking whether the name is . or ..
* fix locking of parent directory for ISDOTDOT case
* call cache_enter() always (even for . and ..)
* vnodeops array: add entry for vop_fcntl_desc, remove unnecessary casts

worth of data under NetBSD -- FreeBSD bread() seems to be able to
return more data and code counted with it
it's possible to actually mount NTFS volume now
