h_OtherHolds_r will never return 0 if we mask our own hold
bit before calling it. however we must be careful to mask before h_TossStuff_r
so we aren't still "holding" then
otherwise just release our hold

====================
remove extra ) which snuck in
previously and since 3.5 rx enhancements fileserver would delay 3 seconds
on sending an rx abort when the abort was the 11th or more occurance of
the same error on the same call. the problem was fetchstatus/bulkstatus
on a directory on which you have "l" but not "r" would take forever after the
first 5 files (bulkstatus and then fetchstatus on each file, 2*5=10)
so in FetchStatus and BulkStatus stubs we suppress repeated errors from
Check_PermissionRights *only*, which has the effect of suppressing the
problem without removing the theoretical benefit of avoiding letting any
one client throw requests at as as fast as we can abort them unless those
requests happen to be fetch/bulkstat requests which fail a permission check,
but in order to avoid that we'd also need to cache what they last tried
to stat, and then things would get ugly.
according to jeff:
- Renames the top-level 'install' target to 'build'. This should be
transparent, since no one should be using that.
- Improves on Sam's dirpath patches, by splitting out server binaries
into separate bin, sbin, and libexec directories in GCS mode (these
are all /usr/afs/bin in Transarc mode).
- Updates the top-level 'all' target so that it builds the software
but does not generate a dest tree. Top-level 'lib' and 'include'
directories are generated to hold the intermediate libraries and headers
used during the build.
- Adds a new top-level 'install' target, which installs things in the
appropriate directories under ${DESTDIR}, based on configure's install
directories plus the extras added by Sam's patch.
- Adds a new top-level 'dest' target, which creates an old-style dest
directory under ${DEST}. The ${DEST} variable defaults to the
traditional value of ${SRCDIR_PARENT}/${SYS_NAME}/dest. Note that
this variable used to be called ${DESTDIR}; it was renamed to avoid
conflicts with the de facto standard usage of ${DESTDIR}.

remove unused function
"First, some background: The AFS Fileserver tries really hard to keep
track of all the "interfaces" of a client. Generally this is for a
multi-homed client, so that the server realizes that you are the same
client when you come from multiple addresses. However, this also
winds up applying to a mobile host whose IP address changes over time.
When the Fileserver sees a "new" address, it asks the client for its
Uuid and, if that Uuid already exists, it adds this new address to the
list of interfaces for the existing host. However, it keeps a
callback connection open to the original address.
Here's the problem: Assume the client has callbacks registered with
the server and then disappears from the network. While the client is
off the net, someone else makes a change that causes that callback to
be broken. The fileserver can't reach the client, so the break gets
added to the delayed callback list. The logic is such that no client
requests will be processed by a host while there are outstanding
delayed callbacks to that client.
Now, if the client comes back on the same IP Address, everything works
fine. The fileserver uses the cached callback connection and the
callbacks are cleared successfully. However, if the client returns to
the network under a different address, this new address is added to
the existing host structure and then the delayed callbacks are
attempted. Unfortunately it is using the (invalid) cached connection
to the old IP Address, so the delayed break fails. Therefore, this
client is locked out of the fileserver until:
1) the fileserver reboots,
2) the client returns to the original IP Address, or
3) All the callbacks timeout on their own.
This patch will fix this problem. When the client makes a request and
the fileserver tries to break the delayed callbacks, if the breaking
fails then the fileserver will attempt to find a 'working' interface
by probing all the host interfaces for one that responds with the
correct Uuid. If that succeeds then it resets the cached callback
connection and then breaks the delayed callbacks, thereby regaining
the connection to the client and proceeding with the proper cleanup
before the original request is completed."
" Extensions used by MR-AFS in the client. I have added only two
pioctl-calls which are used by the "fs"-command for a large number
of MR-AFS specific subcommands. With this modification also the
data type afs_int64 is introduced because MR-AFS supports large files.
afs_int64 is either "long long" or a structure consisting of two
32-bit numbers. We are already running on rs_aix42 a fully large-file
capable AFS-client, but these changes are still in a beta test and
not yet added here."
