a probe name. When dtrace -G builds up a DOF section for the specified
provider(s), the probe function names are truncated to fit in this limit.
The DOF is later used to build the symbol table for the generated object
file, so the table can end up with truncated references, causing link
errors.
Instead of potentially truncating symbol table entries, write the full
function name to the DOF string table and allow the kernel to enforce the
128-byte function name limit when a process attempts to load its DOF.

ZFS large block support.
Please note that booting from datasets that have recordsize greater
than 128KB is not supported (but it's Okay to enable the feature on
the pool). This *may* remain unchanged because of memory constraint.

caution is advised.

Initialize tqent_flags in the userland taskq implementation. Without
this the assertion of tq->tq_freelist != NULL may fail in taskq_destroy.
The problem is that tqent_flags is never initialized in the userland
implementation while the kernel one does initialize it. Without proper
initialization, the flag may have its lowest bit set, making it treated
as TQENT_FLAG_PREALLOC and never removing taskq_ent_t from tq_freelist.

- Limit ARC for zdb at 256MB. zdb do not typically revisit data
in the ARC.
- Increase default max_inflight from 200 to 1000 (can be overriden
by -I) so we can queue more I/Os when doing scrubbing.
- Print status while loading meataslabs for leak detection.

modifications to libproc to support fetching the CTF info for a given file.
With this change, dtrace(1) is able to resolve type info for function and
USDT probe arguments, and function return values. In particular, the args[n]
syntax should now work for referencing arguments of userland probes,
provided that the requisite CTF info is available.
The uctf tests pass if the test programs are compiled with CTF info. The
current infrastructure around the DTrace test suite doesn't support this
yet.

This errno value is emitted by dsl_props_set_check() in
sys/cddl/contrib/opensolaris/uts/common/fs/zfs/dsl_prop.c, and
is used to mean that the property value is too long. For the record,
the maximum length is ZAP_MAXVALUELEN, which is 8*1024 bytes.
Instead of claiming an unknown error (and abort()ing), provide
something more specific to the scenario involved. As far as I
can tell, E2BIG is not emitted for any other scenario.

This change modified the value returned by
dsl_props_set_check(), so that it can distinguish between
a name that's too long and a value that's too long, but
libzfs was not updated accordingly.
