to recode Unicode names to other representation, like encoding form
or national character/code sets. This replaces the ugly NTFS_U28() hack.
Use these hooks to encode the filenames to UTF-8.
ntnode->ntmp->ntm_* values
ntfs_inactivate(): as NTFS doesn't support any filesystem changes,
it's not needed to check whether the file handle is stale;
the check was bogus anyway - besides the value of vp->v_usecount
was checked with unlocked vnode, the vnode was unnecessarily
_always_ recycled when the filesystem containing it has been
mounted with mask (-i parameter to mount_ntfs(1))
not specified or 0 -- unbelievable, but true
ntfs_reclaim(): don't call VOP_UNLOCK() even on FreeBSD - it's not
done for any other their filesystem, so it should not be done even
for NTFS
ntfs_access(): remove the commented-out check for immutable flag, it doesn't
make sense for NTFS
other miscelaneous cosmetic cleanups
VOP__UNLOCK() macros, g/c VOP__LOCK()
add some comments
use LK_RETRY flag as appropriate
g/c the FreeBSD vnode_pager_uncache() staff, as was done in FreeBSD tree a while
ago (actually, when they merged the first round of NetBSD patches)
use VN_LOCK() & VOP__UNLOCK() consistently throughout the code instead
of vn_lock() and VOP_UNLOCK()
minor whitespace changes
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
