Stop the EXT4 filesystem from using iget() and read_inode(). Replace
ext4_read_inode() with ext4_iget(), and call that instead of iget().
ext4_iget() then uses iget_locked() directly and returns a proper error code
instead of an inode in the event of an error.ext4_fill_super() returns any error incurred when getting the root inode
instead of EINVAL.Signed-off-by: David Howells

Add an ERR_CAST() function to complement ERR_PTR and co. for the purposes

pointer type whilst making it explicit as to what is going on.This provides a replacement for the ERR_PTR(PTR_ERR(p)) construct.

This patchset is for the vmcoreinfo data.
The vmcoreinfo data has the minimum debugging information only for dump
filtering. makedumpfile (dump filtering command) gets it to distinguish
unnecessary pages, and makedumpfile creates a small dumpfile.This patch:
VMCOREINFO_SIZE() should be renamed VMCOREINFO_STRUCT_SIZE() since it's always
returning the size of the struct with a given name. This change would allow
VMCOREINFO_TYPEDEF_SIZE() to simply become VMCOREINFO_SIZE() since it need not
be used exclusively for typedefs.This discussion is the following:

This patchset adds a flags variable to reserve_bootmem() and uses the
BOOTMEM_EXCLUSIVE flag in crashkernel reservation code to detect collisions
between crashkernel area and already used memory.This patch:
Change the reserve_bootmem() function to accept a new flag BOOTMEM_EXCLUSIVE.
If that flag is set, the function returns with -EBUSY if the memory already
has been reserved in the past. This is to avoid conflicts.Because that code runs before SMP initialisation, there's no race condition
inside reserve_bootmem_core().[akpm@linux-foundation.org: coding-style fixes]

This is a patch for the Compaq ASIC3 multi function chip, found in many
PDAs (iPAQs, HTCs...).It is a simplified version of Paul Sokolovsky's first proposal [1]. With
this code, it is basically a GPIO and IRQ expander. My plan is to add more
features once this patch gets reviewed and accepted.[1] http://lkml.org/lkml/2007/5/1/46

This patch corrects a situation that occurs when one disables all the cpus in
a cpuset.Currently, the disabled (cpu-less) cpuset inherits the cpus of its parent,
which is incorrect because it may then overlap its cpu-exclusive sibling.Tasks of an empty cpuset should be moved to the cpuset which is the parent of
their current cpuset. Or if the parent cpuset has no cpus, to its parent,
etc.And the empty cpuset should be released (if it is flagged notify_on_release).
Depends on the cgroup_scan_tasks() function (proposed by David Rientjes) to
iterate through all tasks in the cpu-less cpuset. We are deliberately
avoiding a walk of the tasklist.[akpm@linux-foundation.org: coding-style fixes]

Provide cgroup_scan_tasks(), which iterates through every task in a cgroup,
calling a test function and a process function for each. And call the process
function without holding the css_set_lock lock.The idea is David Rientjes', predicting that such a function will make it much
easier in the future to extend things that require access to each task in a
cgroup without holding the lock,[akpm@linux-foundation.org: cleanup]

Add a handler "pre_destroy" to cgroup_subsys. It is called before
cgroup_rmdir() checks all subsys's refcnt.I think this is useful for subsys which have some extra refs even if there
are no tasks in cgroup. By adding pre_destroy(), the kernel keeps the rule
"destroy() against subsystem is called only when refcnt=0." and allows css
ref to be used by other objects than tasks.Signed-off-by: KAMEZAWA Hiroyuki

While using memory control cgroup, page-migration under it works as following.
==
1. uncharge all refs at try to unmap.
2. charge regs again remove_migration_ptes()
==
This is simple but has following problems.
==
The page is uncharged and charged back again if *mapped*.
- This means that cgroup before migration can be different from one after
migration
- If page is not mapped but charged as page cache, charge is just ignored
(because not mapped, it will not be uncharged before migration)
This is memory leak.
==
This patch tries to keep memory cgroup at page migration by increasing
one refcnt during it. 3 functions are added.mem_cgroup_prepare_migration() --- increase refcnt of page->page_cgroup
mem_cgroup_end_migration() --- decrease refcnt of page->page_cgroup
mem_cgroup_page_migration() --- copy page->page_cgroup from old page to
new page.During migration
- old page is under PG_locked.
- new page is under PG_locked, too.
- both old page and new page is not on LRU.These 3 facts guarantee that page_cgroup() migration has no race.
Tested and worked well in x86_64/fake-NUMA box.

Nick Piggin pointed out that swap cache and page cache addition routines
could be called from non GFP_KERNEL contexts. This patch makes the
charging routine aware of the gfp context. Charging might fail if the
cgroup is over it's limit, in which case a suitable error is returned.This patch was tested on a Powerpc box. I am still looking at being able

contexts.[kamezawa.hiroyu@jp.fujitsu.com: problem with ZONE_MOVABLE]

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.[hugh@veritas.com: fix swapoff breakage]
