Some people report that they need psmouse module unloaded for suspend to ram/disk to work properly. Let's make port cleanup behave the same way as driver unload. This fixes "bad state" roblem on various HP laptops, such as nx7400. Signed-off-by:

eCryptfs is gobbling a lot of stack in ecryptfs_generate_key_packet_set() because it allocates a temporary memory-hungry ecryptfs_key_record struct. This patch introduces a new kmem_cache for that struct and converts ecryptfs_generate_key_packet_set() to use it. Signed-off-by:

When NFSD receives a write request, the data is typically in a number of 1448 byte segments and writev is used to collect them together. Unfortunately, generic_file_buffered_write passes these to the filesystem one at a time, so an e.g. 32K over-write becomes a series of partial-page writes to each page, causing the filesystem to have to pre-read those pages - wasted effort. generic_file_buffered_write handles one segment of the vector at a time as it has to pre-fault in each segment to avoid deadlocks. When writing from kernel-space (and nfsd does) this is not an issue, so generic_file_buffered_write does not need to break and iovec from nfsd into little pieces. This patch avoids the splitting when get_fs is KERNEL_DS as it is from NFSd. This issue was introduced by commit 6527c2bdAcked-by:

When setting an ACL that lacks inheritable ACEs on a directory, we should set a default ACL of zero length, not a default ACL with all bits denied. Signed-off-by:

J. Bruce Fields authored
We're inserting deny's between some ACEs in order to enforce posix draft acl semantics which prevent permissions from accumulating across entries in an acl. That's fine, but we're doing that by inserting a deny after *every* allow, which is overkill. We shouldn't be adding them in places where they actually make no difference. Also replaced some helper functions for creating acl entries; I prefer just assigning directly to the struct fields--it takes a few more lines, but the field names provide some documentation that I think makes the result easier understand.

Return just the effective permissions, and forget about the mask. It isn't worth the complexity. WARNING: This breaks backwards compatibility with overly-picky nfsv4->posix acl translation, as may has been included in some patched versions of libacl.

J. Bruce Fields authored
The code that splits an incoming nfsv4 ACL into inheritable and effective parts can be combined with the the code that translates each to a posix acl, resulting in simpler code that requires one less pass through the ACL. Signed-off-by:
-
J. Bruce Fields authored
The rfc allows us to be more permissive about the ACL inheritance bits we accept: "If the server supports a single "inherit ACE" flag that applies to both files and directories, the server may reject the request (i.e., requiring the client to set both the file and directory inheritance flags). The server may also accept the request and silently turn on the ACE4_DIRECTORY_INHERIT_ACE flag." Let's take the latter option--the ACL is a complex attribute that could be rejected for a wide variety of reasons, and the protocol gives us little ability to explain the reason for the rejection, so erroring out is a user-unfriendly last resort.

The server name is expected to be a null-terminated string, so we can't pass in the raw client identifier. What's more, the client identifier is just a binary, not necessarily printable, blob. Let's just use the ip address instead. The server name appears to exist just to help debugging by making some printk's more informative. Note that the string is copies into the rpc client structure, so the pointer to the local variable does not outlive the function call. Signed-off-by:

Never mask interrupts immediately upon request. Disabling interrupts in high-performance codepaths is rare, and on the other hand this change could recover lost edges (or even other types of lost interrupts) by conservatively only masking interrupts after they happen. (NOTE: with this change the highlevel irq-disable code still soft-disables this IRQ line - and if such an interrupt happens then the IRQ flow handler keeps the IRQ masked.) Mark i8529A controllers as 'never loses an edge'. Signed-off-by:

Use RCU to avoid the need to acquire tasklist_lock in the single-threaded case of clock_gettime(). It still acquires tasklist_lock when for a (potentially multithreaded) process. This change allows realtime applications to frequently monitor CPU consumption of individual tasks, as requested (and now deployed) by some off-list users. This has been in Ingo Molnar's -rt patchset since late 2005 with no problems reported, and tests successfully on 2.6.20-rc6, so I believe that it is long-since ready for mainline adoption.
