Ricardo M. Correia c0ce3b40f2 Reimplement user kthreads based on pthread thread specific data.
This resolves previous scalabily concerns about the cost of calling
curthread which previously required a list walk.  The kthread address
is now tracked as thread specific data which can be quickly returned.

Brian Behlendorf cfd9e9936f Fix an accidentally introduced formatting issue in zfs output.
Because the local 'index' variable shadows the index() function
it was replaced by 'i'.  Unfortunately when I made this change
I accidentally replaced one instance with 'j' resulting in the
short decimal values being printed incorrectly.

Brian Behlendorf ee435f260c Excessively large stack frames detected.
The 2.6.30 kernel build systems sets -Wframe-larger-than=2048 which causes
a warning to be generated when an individual stack frame exceeds 2048.
This caught the spa_history_log() and dmu_objset_snapshot() functions
which declared a data structure on the stack which contained a char
array of MAXPATHLEN.  This in defined to be 4096 in the linux kernel
and I imagine it is quite large under Solaris as well.  Regardless, the
offending data structures were moved to the heap to correctly keep the
stack depth to a minimum.  We might consider setting this value even
lower to catch additional offenders because we are expecting deep stacks.

Brian Behlendorf 9cabcac115 Required autoconf support for vdev_disk integration with 2.6.30 kernels.
2.6.22 API change
Unused destroy_dirty_buffers arg removed from prototype.

2.6.24 API change
Empty write barriers are now supported and we should use them.

2.6.24 API change
Size argument dropped from bio_endio and bi_end_io, because the
bi_end_io is only called once now when the request is complete.
There is no longer any need for a size argument.  This also means
that partial IO's are no longer possibe and the end_io callback
should not check bi->bi_size.  Finally, the return type was updated
to void.

2.6.28 API change
open/close_bdev_excl() renamed to open/close_bdev_exclusive().

2.6.29 API change
BIO_RW_SYNC renamed to BIO_RW_SYNCIO.

Brian Behlendorf 3a431c68c2 Remove LINUXINCLUDE from autoconf wrapper, breaks 2.6.28+ kernels.
Modern kernel build systems at least post 2.6.16 will set this properly
so we should not.  In fact post 2.6.28 the include headers have moved
under arch so the guess we make here is completely wrong.  Letting
the kernel build system set this ensure it will be correct.  Also
drop the ulimit from the Makefile which, not surprisingly, turns out
to be very non-portable.  If your expecting failures set the ulimit
in your shell before kicking off the test suite.

Brian Behlendorf 1b4dfb80fb Increase buffer size for nvlist for large configurations
It's still not clear to me why the default value here is large
enough Solaris.  I hit this limit again when setting up 120 SATA
drives configured as 15 raidz2 groups each containing 8 drives.
We expect to go bigger so we may just want to spend a little
time and figure out how to make this all dynamic.

Brian Behlendorf bc8c87d2f3 Missed one instance of losetup -f to unused_loop_device change 2009-07-21 17:05:13 -07:00
Brian Behlendorf b9c3c7a2f4 The losetup -f option is unavailable for SLES10 use unused_loop_device()
SLES10 ships util-linux-2.12r-35.30 which does not support the -f option
to losetup.  To avoid this problem the unused_loop_device() function was
added which attempts to find an unused loop device by checking each
/dev/loop* device with losetup to see if it is configured.

Brian Behlendorf 864e44e7e0 Provide correct kthread API semantics using pthreads.
The intent here is to fully remove the previous Solaris thread
implementation so we don't need to simulate both Solaris kernel
and user space thread APIs.  The few user space consumers of the
thread API have been updated to use the kthread API.  In order
to support this we needed to more fully support the kthread API
and that means not doing crazy things like casting a thread id
to a pointer and using that as was done before.  This first
implementation is not effecient but it does provide all the
corrent semantics.  If/when performance becomes and issue we
can and should just natively adopt pthreads which is portable.

Let me finish by saying I'm not proud of any of this and I would
love to see it improved.  However, this slow implementation does
at least provide all the correct kthread API semantics whereas
the previous method of casting the thread ID to a pointer was
dodgy at best.
