that.
- Move the stat() call to fdopendir() and change it's error handling so that
it does not hide errors.
- According to POSIX, fdopendir() transfers ownership of the fd only on
success, so don't close it on failure. XXX: We still make it non-blocking
on failure, but that's nitpicking.
XXX: pullup-7?
There are situations where the underlying filesystem is unreachable
(e.g: NFS) causing symlink resolution to hang. Such a situation
should be avoided by using umount -f -R (force and raw), but while -R
causes the symlink resolution to be skipped in umount(8), the kernel was
still doing it in sys_unmount(). This changes fixes that.
When the -R flag is not given, umount(8) does symlinks resolution through
realpath(3) before calling unmount(2), hence not doing it in the kernel
would not change behavior.
One benefit to do so is to reduce memory used for struct callout;
we can avoid to allocate struct callout for interfaces that don't
use callout.
Requested by uebayasi@.
This change is to obviate the need to run if_slowtimo callbacks that
may sleep inside IFNET_FOREACH. And also by this change we can turn
on MPSAFE of callouts individually.
Discussed with uebayasi@ and riastradh@.
(v4 multicast options off v4 mapped v6 socket) on interface destruction. The
code to clean this up in a true v4 socket was moved to its own function
which is now also called in the corresponding place for v6 sockets on
interface destruction.
IP addresses in the expected outputs looks reversed (in byte order).
It seems the expected outputs had been generated based on source code
with a bug and the bug was fixed by a commit titled "#534 destination
list hashing not endian neutral" by darrenr@.
