2009-12-04blkio: Allow CFQ group IO scheduling even when CFQ is a moduleVivek Goyal
o Now issues of blkio controller and CFQ in module mode should be fixed. Enable the cfq group scheduling support in module mode. Signed-off-by: Vivek Goyal <vgoyal@redhat.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2009-12-04blkio: Implement dynamic io controlling policy registrationVivek Goyal
o One of the goals of block IO controller is that it should be able to support mulitple io control policies, some of which be operational at higher level in storage hierarchy. o To begin with, we had one io controlling policy implemented by CFQ, and I hard coded the CFQ functions called by blkio. This created issues when CFQ is compiled as module. o This patch implements a basic dynamic io controlling policy registration functionality in blkio. This is similar to elevator functionality where ioschedulers register the functions dynamically. o Now in future, when more IO controlling policies are implemented, these can dynakically register with block IO controller.

2009-12-04blkio: Export some symbols from blkio as its user CFQ can be a moduleVivek Goyal
o blkio controller is inside the kernel and cfq makes use of interfaces exported by blkio. CFQ can be a module too, hence export symbols used by CFQ. Signed-off-by: Vivek Goyal <vgoyal@redhat.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>
2009-12-04block: Fix io_context leak after failure of clone with CLONE_IOLouis Rilling
With CLONE_IO, parent's io_context->nr_tasks is incremented, but never decremented whenever copy_process() fails afterwards, which prevents exit_io_context() from calling IO schedulers exit functions. Give a task_struct to exit_io_context(), and call exit_io_context() instead of put_io_context() in copy_process() cleanup path.

2009-12-04block: Fix io_context leak after clone with CLONE_IOLouis Rilling
With CLONE_IO, copy_io() increments both ioc->refcount and ioc->nr_tasks. However exit_io_context() only decrements ioc->refcount if ioc->nr_tasks reaches 0. Always call put_io_context() in exit_io_context(). Signed-off-by: Louis Rilling <louis.rilling@kerlabs.com> Signed-off-by: Jens Axboe <jens.axboe@oracle.com>

2009-12-04ARM: I-cache: flush executable mappings in flush_cache_range()Russell King
Dirk Behme reported instability on ARM11 SMP (VIPT non-aliasing cache) caused by the dynamic linker changing protection on text pages to write GOT entries. The problem is due to an interaction between the write faulting code providing new anonymous pages which are incoherent with the I-cache due to write buffering, and the I-cache not having been invalidated. a4db94d plugs the hole with the data cache coherency. This patch provides the other half of the fix by flushing the I-cache in flush_cache_range() for VM_EXEC VMAs (which is what we have when the region is being made executable again.) This ensures that the I-cache will be up to date with the newly COW'd pages. Note: if users are writing instructions, then they still need to use the ARM sys_cacheflush API to ensure that the caches are correctly synchronized.

2009-12-04ARM: I-cache: avoid flushing in flush_cache_mm()Russell King
flush_cache_mm() is called in two cases: 1. when a process exits, just before the page tables are torn down. We can allow the stale lines to evict themselves over time without causing any harm. 2. when a process forks, and we've allocated a new ASID. The instruction cache issues are dealt with as pages are brought into the new process address space. Flushing the I-cache here is therefore unnecessary. However, we must keep the VIPT aliasing D-cache flush to ensure that any dirty cache lines are not written back after the pages have been reallocated for some other use - which would result in corruption.

2009-12-04ARM: 5794/1: Flush the D-cache during copy_user_highpage()Catalin Marinas
The I and D caches for copy-on-write pages on processors with write-allocate caches become incoherent causing problems on application relying on CoW for text pages (dynamic linker relocating symbols in a text page). This patch flushes the D-cache for such pages. Cc: Nicolas Pitre <nico@fluxnic.net> Signed-off-by: Catalin Marinas <catalin.marinas@arm.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2009-12-04ARM: Remove __flush_icache_all() from __flush_dcache_page()Russell King
Both call sites for __flush_dcache_page() end up calling __flush_icache_all() themselves, so having __flush_dcache_page() do this as well is wasteful. Remove the duplicated icache flushing. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
