* [XFS] Remove unused variable in ktrace_free()Lachlan McIlroy2008-12-051-7/+2
| | | | | | | | | entries_size is probably left over from when we used to pass the size to kmem_free(). Signed-off-by: Lachlan McIlroy <lachlan@sgi.com> Reviewed-by: Christoph Hellwig <hch@infradead.org> Reviewed-by: Eric Sandeen <sandeen@sandeen.net>
* [XFS] Remove unused arg from kmem_free()Denys Vlasenko2008-07-281-2/+2
| | | | | | | | | | | | | | kmem_free() function takes (ptr, size) arguments but doesn't actually use second one. This patch removes size argument from all callsites.

* [XFS] Use power-of-2 sized buffers to reduce overheadDavid Chinner2008-04-181-8/+14
| | | | | | | | | | | | | | | | | | Now that the ktrace_enter() code is using atomics, the non-power-of-2 buffer sizes - which require modulus operations to get the index - are showing up as using substantial CPU in the profiles. Force the buffer sizes to be rounded up to the nearest power of two and use masking rather than modulus operations to convert the index counter to the buffer index. This reduces ktrace_enter overhead to 8% of a CPU time, and again almost halves the trace intensive test runtime.

* [XFS] Use atomic counters for ktrace buffer indexesDavid Chinner2008-04-181-13/+8
| | | | | | | | | | | | | | | ktrace_enter() is consuming vast amounts of CPU time due to the use of a single global lock for protecting buffer index increments. Change it to use per-buffer atomic counters - this reduces ktrace_enter() overhead during a trace intensive test on a 4p machine from 58% of all CPU time to 12% and halves test runtime.

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
