d_splice_alias now drops the inode reference on error, so we
need to grab an extra one to make sure that the inode doesn't
go away, and release it when done if there was no error.
For kernels that may not drop the reference, provide an
additional iput() within an ifdef. This could be hooked up
to a configure option to allow building a module for a kernel
that is known not to drop the reference on error. That hook
is not provided here. Affected kernels should be the early
3.17 ones (3.17 - 3.17.2); 3.16 and older kernels should not
return errors here.

Commit b5de4a9f removed our key_type 'match' function for kernels that
do not have such a 'match' function pointer. However, this added a
configure test where we are supposed to fail for the "new" behavior,
which is discouraged.
This causes an actual problem, because this test will fail on at least
RHEL5, due to arguably unrelated reasons (the header file for the
relevant struct is in key.h instead of key-type.h). And so, in that
situation we avoid defining a 'match' function callback, meaning our
'match' function callback is NULL, which causes a panic when we try to
actually look up keys for a PAG.
To fix this, transform the 'match' config test into one where we
succeed for the "new" behavior. We do this by testing for the
existence of the new functionality that replaced the old 'match'
function, which is the match_preparse function (specifically, the
'cmp' field in the structure accepted by match_preparse). This should
cause unrelated compilation errors to cause us to revert to the "old"
behavior instead of the "new" behavior. At worst, this should cause
build issues if we get the config test wrong (since we will try to use
the 'match' function definition that does not exist), instead of
panicing at runtime.
Note that while we test for key_type.match_preparse, we don't actually
use that function, since our 'match' functionality is the same as the
default behavior (according to b5de4a9f). So, we can avoid defining
any such function for newer kernels.
Thanks to Stephan Wiesand for bisecting this issue.

Currently, we use sock_create to create our Rx socket. This means that
accesses to that socket (sendmsg, recvmsg) are subject to SELinux
restrictions. For all recvmsg accesses and some sendmsg accesses, this
doesn't matter, since the access will be performed by one of our
kernel threads (running as kernel_t or something similar, which is
unrestricted). Such as: the rx listener, a background daemon, the rx
event thread, etc.
However, sometimes we do run in the context of a normal user process.
For some RPCs like FetchStatus, we tend to run the RPC in the
accessing user thread, which can result in us sendmsg()ing the data
packets with the initial arguments in the user thread. We can also
send delayed ACKs via rx_EndCall, and possibly a variety of other
scenarios.
In any of these situations when we are sendmsg()ing from a user
thread, SELinux can prevent us from sending to the socket, if the
calling user thread context is not able to write to an afs_t
udp_socket. This will result in packets not being sent immediately,
but the packets will be resent later, so access will work, but appear
very slow. This can easily happen for processes that are specifically
constrained by SELinux; for example, webservers are often constrained,
even if most of the rest of the system is not. This can be noticed by
seeing the 'resends' and 'sendFailed' counters rising in 'rxdebug
-rxstat', as well as noticing SELinux access failures if 'dontaudit'
rules are ignored.
To avoid this, use sock_create_kern to create the Rx socket, to
indicate that this is a socket for use by kernel code, and not
accessible by a user. This should cause us to bypass any LSM
restrictions (SELinux, AppArmor, etc). Add a configure check for this,
since this function has not always existed, according to

Convert the readdir function so that it can be used as the new
"iterate" file operation. This new operation is passed a context
that contains a pointer to the filldir function and the offset.
The context is passed into the new dir_emit function that will
call the function specified by the context.
The new dir_emit function returns true on success, so we must be
careful about how we check for failure since this is different
behaviour from what filldir currently does.

In kernels before 027445c3, the functions generic_file_aio_read and
generic_file_aio_write, as well as the fs operations aio_read and
aio_write, do not deal with iovecs but rather just use a single
buffer. Detect this, so our aio_read and aio_write implementations
have the correct signatures.
This removes several warnings on such kernels.

Commit 6c509601 uses the vn_renamepath when we are building on Solaris
11. However, some recent patch level of Solaris 10 (more recent than
stock 10u10) has the same problem fixed by that commit, where
vn_setpath takes an additional argument. So instead, just test for the
existence of vn_renamepath itself, so we also use it on Solaris 10
when we can.
Thanks to Rich Sudlow for reporting this.

Solaris 11+ has ncurses.h in ncurses/ncurses.h. Look for it there.
Without this, on Solaris 11.1 we will detect libncurses automatically
(because it lives in /usr/lib), but not ncurses.h (since it is in
ncurses/ncurses.h, not ncurses.h). So, we will fall back to curses.h,
but will try to link to libncurses, which, as you might guess, fails
with various undefined symbols.
