fstatvfs kept the guest struct statvfs and the sfs2svfs conversion from
the kernel's statfs to itself. Both move to include/Statvfs.hpp so that
statvfs can convert a volume the same way without opening the path.
Nothing changes for fstatvfs.
XPSemu (PPSA97358) imports eleven posix_spawn calls from
libSceLibcInternal.prx, one reference each, and no call site is known.
Predicted stop (import order, not measured), behind isnanf (idx 296):
`FAIL: unresolved ELF import 44hlATrd47U from libSceLibcInternal.prx`
(posix_spawnattr_init, idx 347), followed by p--TkNVsXjA, LG6O0oW9bQU,
Sj7y+JO5PcM, Ud8CbISKRGM, Hq9-2AMG+ks, IUfBO5UIZNc, Heh4KJwyoX8 (348-355),
UV4m0bznVtU, Ani6e+T-y6Q and 3Nr9caNHhyg (379-381).
The nine object calls follow FreeBSD release/11.4.0 (8c639945a445)
lib/libc/gen/posix_spawn.c: posix_spawnattr_init allocates a zeroed
attribute object (ENOMEM on failure), _destroy frees it, _setflags and
_setsigdefault store the value; posix_spawn_file_actions_init allocates an
empty list (-1 on failure, as in 11.4), _destroy frees it with its
entries, and _addopen (path copied), _adddup2 and _addclose append in
order after returning EBADF for a negative descriptor. Null or
uninitialized objects, which FreeBSD dereferences, throw.
posix_spawn and posix_spawnp throw "process creation not implemented",
as execvp does: FreeBSD validates no argument before rfork/vfork, and no
child process can be created here. TechnicalDebt records them.
guest_posix_spawn covers the attribute round trips, the recorded action
sequence, the EBADF cases and the throws. NIDs computed with
tools/nid_names.py and present in aerolib.
