[PATCH 13/24] CacheFiles: Permit the page lock state to be monitored

Add a function to install a monitor on the page lock waitqueue for a particular page, thus allowing the page being unlocked to be detected. This is used by CacheFiles to detect read completion on a page in the backing filesystem so that it can then copy the data to the waiting netfs page.

[PATCH 09/24] FS-Cache: Provide an add_wait_queue_tail() function

[PATCH 07/24] FS-Cache: Release page->private after failed readahead

The attached patch causes read_cache_pages() to release page-private data on a page for which add_to_page_cache() fails or the filler function fails. This permits pages with caching references associated with them to be cleaned up. The invalidatepage() address space op is called (indirectly) to

[PATCH 08/24] FS-Cache: Recruit a couple of page flags for cache management

Recruit a couple of page flags to aid in cache management. The following extra flags are defined: (1) PG_fscache (PG_owner_priv_2) The marked page is backed by a local cache and is pinning resources in the cache driver. (2) PG_fscache_write (PG_owner_priv_3) The marked page

[PATCH 06/24] CRED: Request a credential record for a kernel service

Request a credential record for the named kernel service. This produces a cred struct with appropriate DAC and MAC controls for effecting that service. It may be used to override the credentials on a task to do work on that task's behalf. Signed-off-by: David Howells <[EMAIL PROTECTED]> ---

[PATCH 04/24] CRED: Move the effective capabilities into the cred struct

Move the effective capabilities mask from the task struct into the credentials record. Note that the effective capabilities mask in the cred struct shadows that in the task_struct because a thread can have its capabilities masks changed by another thread. The shadowing is performed by

[PATCH 02/24] CRED: Split the task security data and move part of it into struct cred

Move into the cred struct the part of the task security data that defines how a task acts upon an object. The part that defines how something acts upon a task remains attached to the task. For SELinux this requires some of task_security_struct to be split off into cred_security_struct which is

[PATCH 4/5] ibmebus: Move to of_device and of_platform_driver, match eHCA and eHEA drivers

Replace struct ibmebus_dev and struct ibmebus_driver with struct of_device and struct of_platform_driver, respectively. Match the external ibmebus interface and drivers using it. Signed-off-by: Joachim Fenkes <[EMAIL PROTECTED]> --- drivers/infiniband/hw/ehca/ehca_classes.h |2 +-

[PATCH 3/5] ibmebus: Add device creation and bus probing based on of_device

The devtree root is now searched for devices matching a built-in whitelist during boot, so these devices appear on the bus from the beginning. It is still possible to manually add/remove devices to/from the bus by using the probe/remove sysfs interface. Also, when a device driver registers itself,

[PATCH 2/5] ibmebus: Remove bus match/probe/remove functions

Remove old code that will be replaced by rewritten and shorter functions in the next patch. Keep struct ibmebus_dev and struct ibmebus_driver for now, but replace ibmebus_{,un}register_driver() by dummy functions. This way, the kernel will still compile and run during the transition and git bisect

[PATCH 1/5] PowerPC: Move of_device allocation into of_device.[ch]

Extract generic of_device allocation code from of_platform_device_create() and move it into of_device.[ch], called of_device_alloc(). Also, there's now of_device_free() which puts the device node. This way, bus drivers that build on of_platform (like ibmebus will) can build upon this code instead

[PATCH 0/5] [REPOST] PowerPC: ibmebus refactoring and fixes

This patchset will merge the ibmebus and of_platform bus drivers by basing a lot of ibmebus functionality on of_platform code and adding the features specific to ibmebus on top of that. This is a repost of my previous patchset incorporating Arnd's comments. I split the actual ibmebus rework into
