* Memory controller improve user interfaceBalbir Singh2008-02-071-5/+7
| | | | | | | | | | | | | | | | | | | | | | | | | Change the interface to use bytes instead of pages. Page sizes can vary across platforms and configurations. A new strategy routine has been added to the resource counters infrastructure to format the data as desired. Suggested by David Rientjes, Andrew Morton and Herbert Poetzl Tested on a UML setup with the config for memory control enabled.

* Memory controller: add per cgroup LRU and reclaimBalbir Singh2008-02-073-0/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the page_cgroup to the per cgroup LRU. The reclaim algorithm has been modified to make the isolate_lru_pages() as a pluggable component.

* Memory controller: memory accountingBalbir Singh2008-02-071-0/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add the accounting hooks. The accounting is carried out for RSS and Page Cache (unmapped) pages. There is now a common limit and accounting for both. The RSS accounting is accounted at page_add_*_rmap() and page_remove_rmap() time. Page cache is accounted at add_to_page_cache(), __delete_from_page_cache(). Swap cache is also accounted for. Each page's page_cgroup is protected with the last bit of the page_cgroup pointer, this makes handling of race conditions involving simultaneous mappings of a page easier. A reference count is kept in the page_cgroup to deal with cases where a page might be unmapped from the RSS of all tasks, but still lives in the page cache. Credits go to Vaidyanathan Srinivasan for helping with reference counting work of the page cgroup. Almost all of the page cache accounting code has help from Vaidyanathan Srinivasan.

| | | | | | | | | | | | | | | | | | | Rename old vfs_ioctl to do_ioctl, because the comment above it clearly indicates that it is an internal function not to be exported to modules; therefore it should have a more traditional do_XXX name. The new do_ioctl is exported in fs.h but not to modules. Rename the old do_ioctl to vfs_ioctl because the names vfs_XXX should preferably be reserved to callable VFS functions which modules may call, as many other vfs_XXX functions already do. Export the new vfs_ioctl to GPL modules so others can use it (including Unionfs and eCryptfs). Add DocBook for new vfs_ioctl.

Removing these methods allows drivers to have all transaction parameters available at 'prep' time, saves two function pointers in struct dma_async_tx_descriptor, and reduces the number of indirect branches.. A consequence of moving this data to the 'prep' routine is that multi-source routines like async_xor need temporary storage to convert an array of linear addresses into an array of dma addresses. In order to keep the same stack footprint of the previous implementation the input array is reused as storage for the dma addresses. This requires that sizeof(dma_addr_t) be less than or equal to sizeof(void *). As a consequence CONFIG_DMADEVICES now depends on !CONFIG_HIGHMEM64G. It also requires that drivers be able to make descriptor resources available when the 'prep' routine is polled.

This is not ideal for DDF and other metadata schemes which have their own partitioning concept. So for externally managed metadata, just claim the device for md in general, require that "offset" and "size" are set properly for each device, and make sure that if a device is included in different arrays then the active sections do not overlap. This involves adding another flag to the rdev which makes it awkward to set "->flags = 0" to clear certain flags. So now clear flags explicitly by name when we want to clear things.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This allows userspace to control resync/reshape progress and synchronise it with other activities, such as shared access in a SAN, or backing up critical sections during a tricky reshape. Writing a number of sectors (which must be a multiple of the chunk size if such is meaningful) causes a resync to pause when it gets to that point.

Alternates are non-persistant ('none') where there is no stable metadata - after the array is stopped there is no record of it's status - and internal which can be version 0.90 or version 1.x These are selected by writing to the 'metadata' attribute. - move the updating of superblocks (sync_sbs) to after we have checked if there are any superblocks or not. - New array state 'write_pending'. This means that the metadata records the array as 'clean', but a write has been requested, so the metadata has to be updated to record a 'dirty' array before the write can continue. This change is reported to md by writing 'active' to the array_state attribute. - tidy up marking of sb_dirty: - don't set sb_dirty when resync finishes as md_check_recovery calls md_update_sb when the sync thread finishes anyway. - Don't set sb_dirty in multipath_run as the array might not be dirty. - don't mark superblock dirty when switching to 'clean' if there is no internal superblock (if external, userspace can choose to update the superblock whenever it chooses to).

* | | | md: Update md bitmap during resync.NeilBrown2008-02-061-0/+3

Rather the entire bitmap is updated when the resync completes. This is because there is no guarentee that resync requests will complete in order, and tracking each request individually is unnecessarily burdensome. However there is value in regularly updating the bitmap, so add code to periodically pause while all pending sync requests complete, then update the bitmap. Doing this only every few seconds (the same as the bitmap update time) does not notciably affect resync performance.
