Brian Behlendorf 51a936233f Merge branch 'fix-stack-dsl_dataset_destroy' into refs/top-bases/fix-branch 2010-06-29 10:12:03 -07:00
Brian Behlendorf 7334572416 Reduce stack usage by dsl_dataset_destroy()
Move dsl_dataset_t local variable from the stack to the heap.
This reduces the stack usage of this function from 2048 bytes
to 176 bytes for x84_64 arches.

Brian Behlendorf 52bb0d8e75 Ensure zio_bad_cksum_t is initialized
This may not strictly be needed but it does keep gcc happy.  We
should keep our eye on this though if the extra bcopy significantly
impacts performance.  It may.

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 0c11631b02 Fix for fix-stack-dmu_objset_snapshot should be 'sn' not '&sn'
I missed a instanse of removing the & operator when reducing the
stack usage in this function.  This unfortunately doesn't cause
a compile warning but it is does cause ztest failures.  Anyway,
update the topic branch to correct this mistake.

Brian Behlendorf e163b08ba3 Add fix-stack-dmu_objset_snapshot topic branch
Reduce stack usage by 276 bytes by moving the snaparg struct from the
stack to the heap.  We have limited stack space we must not waste.

Brian Behlendorf bbdb8184ec Add fix-stack-noinline topic branch
Certain function must never be automatically inlined by gcc because
they are stack heavy or called recursively.  This patch flags all
such functions I have found as 'noinline' to prevent gcc from making
the optimization.

Brian Behlendorf 869764f64d Add fix-stack-dsl_deleg_get topic branch
Reduce stack usage in dsl_deleg_get, gcc flagged it as consuming a
whopping 1040 bytes or potentially 1/4 of a 4K stack.  This patch
moves all the large structures and buffer off the stack and on to
the heap.  This includes 2 zap_cursor_t structs each 52 bytes in
size, 2 zap_attribute_t structs each 280 bytes in size, and 1
256 byte char array.  The total saves on the stack is 880 bytes
after you account for the 5 new pointers added.

Also the source buffer length has been increased from MAXNAMELEN
to MAXNAMELEN+strlen(MOS_DIR_NAME)+1 as described by the comment in
dsl_dir_name().  A buffer overrun may have been possible with the
slightly smaller buffer.

Brian Behlendorf b8cc785fb6 Add fix-stack-lzjb topic branch
Reduce kernel stack usage by lzjb_compress() by moving uint16 array
off the stack and on to the heap.  The exact performance implications
of this I have not measured but we absolutely need to keep stack
usage to a minimum.  If/when this becomes and issue we optimize.

Brian Behlendorf f61a7ce9e1 Add fix-kstat-xuio topic branch
Move xiou stat structures from a header to the dmu.c source as is
done with all the other kstat interfaces.  This information is local
to dmu.c registered the xuio kstat and should stay that way.

Brian Behlendorf f3a61f709d Add fix-metaslab topic branch
If your only going to allow one allocator to be used and it is defined
at compile time there is no point including the others in the build.
This patch could/should be refined for Linux to make the metaslab
configurable at run time.  That might be a bit tricky however since
you would need to quiese all IO.  Short of that making it configurable
as a module load option would be a reasonable compromise.

Brian Behlendorf 6cf7f7c9df Add fix-current topic branch
In the linux kernel 'current' is defined to mean the current process
and can never be used as a local variable in a function.  Simply
replace all usage of 'current' with 'curr' in this function.

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

Almost exclusively this patch handled the addition of another char
array to the zfs_cmd_t structure.  Unfortunately c90 doesn't allow
zero filling the entire struct with the '= { 0 };' shorthand.

Originally these changes were on other gcc-* topic branches but
because c90 touches the same bit of code and I'd like to keep all
the gcc-* branches completely parallel I've moved these few bits
over here.  This is one of the downsides of not just having one
big patch stack.

Brian Behlendorf fb72c6ef81 Revert gcc-shadow using -Wno-shadow I can live with
While I would rather fix all the instances where something is shadowed
it complicates tracking the OpenSolaris code where they either don't
seem to care or have different conflicts.  Anyway, this ends up being
more simply gratutous change than I care for.
