Ned Bass 49177b6ab7 Use inline version of __zio_execute 
Explicitly call to inline version to minimize stack usage.

Ned Bass 2e3c7a06c2 Wrap zio_execute() to enable inlining 
Implement zio_execute() as a wrapper around the static function
__zio_execute() so that we can force  __zio_execute() to be inlined.
This reduces stack overhead which is important because __zio_execute()
is called recursively in several zio code paths.  zio_execute() itself
cannot be inlined because it is externally visible.

Brian Behlendorf 52c23142d4 Revert "Inline zio_execute() to reduce stack use" 
This reverts commit 411dd65af1.

gcc version 4.1.2 does not like having differing prototypes
for zio_execute, one version in the .c with inline and one
version in the .h without.  Thus I'm reverting this change
and we'll see how critical this particular stack reduction is.

Ned Bass d5658668e0 Reduce stack usage of zio_done 
Eliminated local variables pointing to members of the zio struct.
Just refer to the struct members directly.  This saved about 32 bytes per
call, but this function can be called recurisvely up to 19 levels deep,
so we potentially save up to 608 bytes.

Ned Bass 411dd65af1 Inline zio_execute() to reduce stack use 
Deep recursive call chains are contributing to segfaults in ztest due to
heavy stack use.  Inlining zio_execute() helps reduce the stack depth of
the zio_notify_parent() -> zio_execute() -> zio_wait() recursive cycle.
I am no longer seeing ztest segfaults in this code path with this change.

Ned Bass dd72f3d647 Inline zio_notify_parent() to reduce stack use 
Deep recursive call chains are contributing to segfaults in ztest due
to heavy stack use.  Inlining zio_notify_parent() helps reduce the
stack depth of the zio_notify_parent() -> zio_execute() -> zio_done()
recursive cycle.  I am no longer seeing ztest segfaults in this code
path with this change combined with the zio_done() stack reduction in
the previous commit.

Ricardo M. Correia 4ca4dfe9bb Fix taskq_dispatch() call in zio_taskq_dispatch(). 
The feature branch 'fix-taskq' in Linux's ZFS tree changes the taskq_dispatch()
flag from TQ_SLEEP to TQ_NOSLEEP to avoid sleeping in some circumstances.

However, this has the side effect that taskq_dispatch() now may fail, and since
the return code was not even being checked, it could lead to zio's not being
scheduled to execute.

I'm fixing this in a simplistic but not very elegant way, by just looping until
taskq_dispatch() succeeds.

Brian Behlendorf 6914386b85 Never sleep under taskq_dispatch() 
There are cases where under Linux it is not safe to sleep in
taskq_dispatch().  Rather than adding Linux specific code to
detect these cases I opted to keep it simple and just never
allow a sleep here.  The impact of this should be minimal.

Brian Behlendorf 49ad53c46f Update fix-taskq to never sleep at interrupt time 
Updated fix to detect if we are in an interrupt and only sleep if it
is safe to do some.  I guess it must be safe to sleep under Solaris
this must be handled in a sort interrupt handler there
