This patch adds an atomic create+open operation. This does not yet work if
the file type changes between lookup and create+open, but solves the
permission checking problems for the separte create and open methods.Signed-off-by: Miklos Szeredi

Add a new access call, which will only be called if ->permission is invoked
from sys_access(). In all other cases permission checking is delayed until
the actual filesystem operation.Signed-off-by: Miklos Szeredi

This patch extends the iattr structure with a file pointer memeber, and adds
an ATTR_FILE validity flag for this member.This is set if do_truncate() is invoked from ftruncate() or from
do_coredump().The change is source and binary compatible.

The sys_ptrace boilerplate code (everything outside the big switch
statement for the arch-specific requests) is shared by most architectures.
This patch moves it to kernel/ptrace.c and leaves the arch-specific code as
arch_ptrace.Some architectures have a too different ptrace so we have to exclude them.
They continue to keep their implementations. For sh64 I had to add a
sh64_ptrace wrapper because it does some initialization on the first call.
For um I removed an ifdefed SUBARCH_PTRACE_SPECIAL block, but
SUBARCH_PTRACE_SPECIAL isn't defined anywhere in the tree.Signed-off-by: Christoph Hellwig

There is a memory leak possible in dentry_open(). If get_empty_filp()
fails, then the references to dentry and mnt need to be released. The

The code for FUTEX_WAKE_OP calls an arch callback,
futex_atomic_op_inuser(). That callback can return an error code, but
currently the caller assumes any error is EFAULT, and will try various
things to resolve the fault before eventually giving up with EFAULT
(regardless of the original error code). This is not a theoretical case -
arch callbacks currently return -ENOSYS if the opcode they are given is
bogus.This patch alters the code to detect non-EFAULT errors and return them
directly to the user.Of course, whether -ENOSYS is the correct return value for the bogus opcode
case, or whether EINVAL would be more appropriate is another question.Signed-off-by: David Gibson

AIO was adding a new context's max requests to the global total before
testing if that resulting total was over the global limit. This let
innocent tasks get their new limit tested along with a racing guilty task
that was crossing the limit. This serializes the _nr accounting with a
spinlock It also switches to using unsigned long for the global totals.
Individual contexts are still limited to an unsigned int's worth of
requests by the syscall interface.The problem and fix were verified with a simple program that spun creating
and destroying a context while holding on to another long lived context.
Before the patch a task creating a tiny context could get a spurious EAGAIN
if it raced with a task creating a very large context that overran the
limit.Signed-off-by: Zach Brown

Reiser4 uses radix trees to solve a trouble reiser4_readdir has serving nfs
requests.Unfortunately, radix tree api lacks an operation suitable for modifying
existing entry. This patch adds radix_tree_lookup_slot which returns pointer

This patch has the changes to support the memory floor fix done in Dell
BIOS. The BIOS incase of packet update mechanism would not accept packet
placed in memory below a cretain address. This address is by default 128K
but can change. The driver now can accept the memory floor if the user
chooses to make it will try to allocate contiguous physical memory above
the memory floor by allocating a set of packets till a valid memory
allocation is made. All the allocates then are freed. This repeats for
everty packet.This patch was created by Michael E Brown and has been tested on 2.6.14-rc5

driver_unregister is not being properly called when the init function
returns an error case. Restructured the return logic such that this and
the other cleanups all happen in one place. Preformed many of the cleanups
that Andrew Morton's patch on Thursday made in tpm_atmel.c. Fixed
Matthieu's concern about writing before discovery.(akpm: rmk said:
This driver is buggy. You must not provide your own release function - it
doesn't solve the problem which the warning (which you get when you don't
provide one) is telling you about.You should convert your device driver over to the replacement dynamic platform
support, once it is merged. IOW, something like:pdev = platform_device_alloc("mydev", id);
if (pdev) {
err = platform_device_add_resources(pdev, &resources,
ARRAY_SIZE(resources));
if (err == 0)
err = platform_device_add_data(pdev, &platform_data,
sizeof(platform_data));
if (err == 0)
err = platform_device_add(pdev);
} else {
err = -ENOMEM;
}
if (err)
platform_device_put(pdev);

There is a wrong BUG in mxser_close.
The BUG is triggered when tty->driver_data == NULL, But in fact this is not
a bug, because tty->driver->close is called even when tty->driver->open
fails.LDD3 tells us to do nothing in such cases.
