[S+Q2 05/19] SLUB: Constants need UL
UL suffix is missing in some constants. Conform to how slab.h uses constants.

[S+Q2 06/19] slub: Check kasprintf results in kmem_cache_init()
Small allocations may fail during slab bringup which is fatal. Add a BUG_ON() so that we fail immediately rather than failing later during sysfs processing.

[S+Q2 09/19] slub: discard_slab_unlock
The sequence of unlocking a slab and freeing occurs multiple times. Put the common into a single function. There is no intend here to use this to enforce a sequencing of events leading up to the discarding of a slab page.

HTC Dream drivers was Re: [linux-pm] suspend blockers & Android integration
Hi! So for people who really care about running a mainline kernel on their android device doing that part first on a generic ARM board in qemu might be much better first step work. On the other hand I've heard that various hardware vendors or parties closed to them are rather annoy... 9 Jul 2010 16:06

People get confused because of the output and some of the items listed no longer have the same relevance in the queued form of SLUB.

[S+Q2 14/19] slub: Move gfpflag masking out of the hotpath
Move the gfpflags masking into the hooks for checkers and into the slowpaths. gfpflag masking requires access to a global variable and thus adds an additional cacheline reference to the hotpaths. If no hooks are active then the gfpflag masking will result in code that the compiler can toss out. Signed-off-by: ... 9 Jul 2010 16:06

[S+Q2 02/19] percpu: make @dyn_size always mean min dyn_size in first chunk init functions
In pcpu_build_alloc_info() and pcpu_embed_first_chunk(), @dyn_size was ssize_t, -1 meant auto-size, 0 forced 0 and positive meant minimum size. There's no use case for forcing 0 and the upcoming early alloc support always requires non-zero dynamic size. Make @dyn_size always mean minimum dyn_size. While at it,... 9 Jul 2010 16:06

[S+Q2 08/19] slub: Use kmem_cache flags to detect if slab is in debugging mode.
The cacheline with the flags is reachable from the hot paths after the percpu allocator changes went in. So there is no need anymore to put a flag into each slab page. Get rid of the SlubDebug flag and use the flags in kmem_cache instead. Acked-by: David Rientjes <rientjes(a)google.com> Signed-off-by: Christoph La... 9 Jul 2010 16:06
