ecryptfs: fixed msync to flush data

When msync is called on a memory mapped file, that
data is not flushed to the disk.

In Linux, msync calls fsync for the file. For ecryptfs,
fsync just calls the lower level file system's fsync.
Changed the ecryptfs fsync code to call filemap_write_and_wait
before calling the lower level fsync.

Addresses the problem described in http://crbug.com/239536

mm: Fix virt_to_page() warning

virt_to_page() is typically implemented as a macro containing a cast so
that it will accept both pointers and unsigned long without causing a
warning.

But MIPS virt_to_page() uses virt_to_phys which is a function so passing
an unsigned long will cause a warning:

    CC      mm/page_alloc.o
  mm/page_alloc.c: In function ‘free_reserved_area’:
  mm/page_alloc.c:5161:3: warning: passing argument 1 of ‘virt_to_phys’ makes pointer from integer without a cast [enabled by default]
  arch/mips/include/asm/io.h:119:100: note: expected ‘const volatile void *’ but argument is of type ‘long unsigned int’

All others users of virt_to_page() in mm/ are passing a void *.

leds: leds-gpio: reserve gpio before using it

This reverts commit a99d76f (leds: leds-gpio: use gpio_request_one)
and commit 2d7c22f (leds: leds-gpio: set devm_gpio_request_one()
flags param correctly) which was a fix of the first one.

The conversion to devm_gpio_request in commit e3b1d44c (leds:
leds-gpio: use devm_gpio_request_one) is not reverted.

The problem is that gpio_cansleep() and gpio_get_value_cansleep()

same bug existed earlier and was fixed similarly in commit d95cbe61

11 years agox86: Fix bit corruption at CPU resume time
Linus Torvalds [Mon, 20 May 2013 18:36:03 +0000 (11:36 -0700)]
x86: Fix bit corruption at CPU resume time

In commit 78d77df71510 ("x86-64, init: Do not set NX bits on non-NX
capable hardware") we added the early_pmd_flags that gets the NX bit set
when a CPU supports NX. However, the new variable was marked __initdata,
because the main _use_ of this is in an __init routine.

However, the bit setting happens from secondary_startup_64(), which is
called not only at bootup, but on every secondary CPU start.  Including
resuming from STR and at CPU hotplug time.  So the value cannot be
__initdata.

Merge branch 'devm_no_resource_check' of git://git./linux/kernel/git/wsa/linux

Pull devm usage cleanup from Wolfram Sang:
 "Lately, I have been experimenting how to improve the devm interface to
  make writing device drivers easier and less error prone while also
  getting rid of its subtle issues.  I think it has more potential but
  still needs work and definately conistency, especiall in its usage.

  The first thing I come up with is a low hanging fruit regarding
  devm_ioremap_resouce().  This function already checks if the passed
  resource is valid and gives an error message if not.  So, we can
  remove similar checks from the drivers and get rid of a bit of code
  and a number of inconsistent error strings.

  This series only removes the unneeded check iff devm_ioremap_resource
  follows platform_get_resource directly.  The previous version tried to
  shuffle code if needed, too, what lead to an embarrasing bug.  It
  turned out to me that shuffling code for all cases found will make the
  automated script too complex, so I am unsure if an automated cleanup
  is the proper tool for this case.  Removing the easy stuff seems
  worthwhile to me, though.

  Despite various architectures and platform dependencies, I managed to
  compile test 45 out of 57 modified files locally using heuristics and
  defconfigs."

Btrfs: use a btrfs bioset instead of abusing bio internals

Btrfs has been pointer tagging bi_private and using bi_bdev
to store the stripe index and mirror number of failed IOs.

As bios bubble back up through the call chain, we use these
to decide if and how to retry our IOs.  They are also used
to count IO failures on a per device basis.

Recently a bio tracepoint was added lead to crashes because
we were abusing bi_bdev.

This commit adds a btrfs bioset, and creates explicit fields
for the mirror number and stripe index.  The plan is to
extend this structure for all of the fields currently in
struct btrfs_bio, which will mean one less kmalloc in
our IO path.

Btrfs: explicitly use global_block_rsv for quota_tree

The quota_tree was set up to use the empty_block_rsv before
which would be problematic when the filesystem is filled up
and ENOSPC happens during internal operations while the quota
tree is updated and COWed (when the btrfs_qgroup_info_item
items) are written. In fact, use_block_rsv() which is used
in btrfs_cow_block() falls back to the global_block_rsv in
this case. But just in order to make it more clear what is
happening, change it to explicitly use the global_block_rsv.

11 years agobtrfs: do away with non-whole_page extent I/O

btrfs: do away with non-whole_page extent I/O

end_bio_extent_readpage computes whole_page based on bv_offset and
bv_len, without taking into account that blk_update_request may modify
them when some of the blocks to be read into a page produce a read
error.  This would cause the read to unlock only part of the file
range associated with the page, which would in turn leave the entire
page locked, which would not only keep the process blocked instead of
returning -EIO to it, but also prevent any further access to the file.

It turns out that btrfs always issues whole-page reads and writes.
The special handling of non-whole_page appears to be a mistake or a
left-over from a time when this wasn't the case.  Indeed,
end_bio_extent_writepage distinguished between whole_page and
non-whole_page writes but behaved identically in both cases!

I've replaced the whole_page computations with warnings, just to be
sure that we're not issuing partial page reads or writes.  The
warnings should probably just go away some time.
