Merged
+might_sleep.patch
Debug patch to catch people calling things like kmalloc(__GFP_WAIT),
down(), etc from inside spinlocks. This is a much stronger test than
the one in schedule(). It's really only effective with CONFIG_PREEMPT=y.
Causes a storm of complaints and stack backtraces at boot due to
drivers/ide/ide-probe.c:init_irq() calling lots of things which it
shouldn't under ide_lock. It will find other bugs.
+set_page_dirty-locking-fix.patch
We don't need to hold mapping->private_lock while moving the page
onto its mapping's dirty_pages list.
+swsusp-feature.patch
Feature for software suspend to force page reclaim. Doesn't work right.
+adaptec-fix.patch
Fix the lockup which happens each time the aic7xxx driver encounters
an IO error.
+remove-page-virtual.patch
Remove page->virtual, hash for it.
+dirty-memory-clamp.patch
Kill off the secret benchmarking feature which allowed the dirty memory
threshold to be exceeded when running dbench. Makes the kernel really
strict about limiting the amount of dirty memory and should make the
buffer_head stripping code more effective.
+mempool-wakeup-fix.patch
Fix a task lockup which can happen in mempool_alloc() when the number
of sleeping tasks exceeds the size of the mempool.
+remove-write_mapping_buffers.patch
Remove the write_mapping_buffers() function. It didn't work out.
+buffer_boundary-scheduling.patch
Use the buffer_boundary() block-mapping hint for scheduling of IO
against indirect blocks. This _does_ work out. Large-file writeback
is now smooth and seekless.
+ll_rw_block-cleanup.patch
Clean up the ll_rw_block() function.
+lseek-ext2_readdir.patch
Remove the lock_kernel() in ext2_readdir(). I'm fairly sure that it's
superfluous, and it was being irritating.
+discontig-no-contig_page_data.patch
Make sure that contig_page_data is undefined on discontigmem builds.
+per-node-zone_normal.patch
Make the normal zone per-node rather than global on the NUMAQ's.
+alloc_pages_node-cleanup.patch
Clean up alloc_pages_node()
+read_barrier_depends.patch
+rcu_ltimer.patch
+dcache_rcu.patch
The dcache RCU code.
I do not intend to send this on to Linus. It is not my area and I
do not understand the code.
But a 15% hit in specweb99 on an 8-way is sigificant and no other
solution has presented itself. So this way, this code gets some extra
testing. Plus clearing away this problem helps us to identify other
bottlenecks.
I shall keep these patches ticking over as a general service to the
people who are interested in, and working on 2.5 performance.
No real progress has been made on the writer-starves-reader problem
which is impacting the `contest' io_fullload test. This is a severe
problem - a streaming write is decreasing read performance from the
same disk by a factor of 4000. Working on it.
