- ifdef out some code that is only used for NO_DEV_PTM
- pass the mountpoint instead of the ptm structure to the implementation
dependent (ptyfs or bsdpty) functions.
- add a function to return the correct ptyfs mountpoint for the current lwp
and the metadata required to interpret it. Callers of namei must now
create a pathbuf and pass it to NDINIT (instead of a string and a
uio_seg), then destroy the pathbuf after the namei session is
complete.
Update all namei call sites accordingly. Add a pathbuf(9) man page and
update namei(9).
The pathbuf interface also now appears in a couple of related
additional places that were passing string/uio_seg pairs that were
later fed into NDINIT. Update other call sites accordingly.
years ago when the kernel was modified to not alter ABI based on
DIAGNOSTIC, and now just call the respective function interfaces
(in lowercase). Plenty of mix'n match upper/lowercase has creeped
into the tree since then. Nuke the macros and convert all callsites
to lowercase.
no functional change
the code that `knows' about /dev/[pt]tyXX names (the BSD ptys) into a separate
file. Make an interface to be used by the tty creating provider. The code
to enable old PTY searching via ptm is enabled via COMPAT_BSDPTY, and it
is turned on by default on all kernels that have compatibility options enabled.
