# $FreeBSD$
2) should understand Rock Ridge
Yes, we have follows function.
o Symbolic Link
o Real Name(long name)
o File Attribute
o Time stamp
o uid, gid
o Devices
o Relocated directories
Except follows:
o POSIX device number mapping
There is some preliminary stuff in there that (ab-)uses the mknod
system call, but this needs a writable filesystem
5) should have name translation enabled by mount flag
Yes. we can disable the Rock Ridge Extension by follows option;
"mount -t isofs -o -norrip /dev/cd0d /cdrom"
6) should run as a user process, and not take up kernel space (cdroms
are slow)
Not yet.
7) ECMA support.
Not yet. we need not only a technical spec but also ECMA format
cd-rom itself!
8) Character set change by SVD ( multi SVD support )
Not yet. We should also hack the other part of system as 8 bit
clean. As far as I know, if you export the cdrom by NFS, the client
can access the 8 bit clean (ie. Solaris Japanese with EUC code )

1. Investiate making ISOFS another UFS shared filesystem (ala FFS/MFS/LFS).
Since it was modelled after the inode code, we might be able to merge
them back. It looks like a separate (but very similar) lookup routine
will be needed due to the associated file stuff.
2. It would be nice to be able to use the vfs_cluster code.
Unfortunately, if the logical block size is smaller than the page size,
it won't work. Also, if throughtput is relatively constant for any
block size (as it is for the HP drive--150kbs) then clustering may not
buy much (or may even hurt when vfs_cluster comes up with a large sync
cluster).
3. Seems like there should be a "notrans" or some such mount option to show
filenames as they really are without lower-casing. Does this make sense?

* Convert a component of a pathname into a pointer to a locked inode.
* This is a very central and rather complicated routine.
* If the filesystem is not maintained in a strict tree hierarchy,
* this can result in a deadlock situation (see comments in code below).
*
* The flag argument is LOOKUP, CREATE, RENAME, or DELETE depending on
* whether the name is to be looked up, created, renamed, or deleted.
* When CREATE, RENAME, or DELETE is specified, information usable in
* creating, renaming, or deleting a directory entry may be calculated.
* If flag has LOCKPARENT or'ed into it and the target of the pathname
* exists, lookup returns both the target and its parent directory locked.
* When creating or renaming and LOCKPARENT is specified, the target may
* not be ".". When deleting and LOCKPARENT is specified, the target may
* be "."., but the caller must check to ensure it does an vrele and iput
* instead of two iputs.
*
* Overall outline of ufs_lookup:
*
* search for name in directory, to found or notfound
* notfound:
* if creating, return locked directory, leaving info on available slots
* else return error
* found:
* if at end of path and deleting, return information to allow delete
* if at end of path and rewriting (RENAME and LOCKPARENT), lock target
* inode and return info to allow rewrite
* if not at end, add name to cache; if at end and neither creating
* nor deleting, add name to cache
*
* NOTE: (LOOKUP | LOCKPARENT) currently returns the parent inode unlocked.
