Did not move the parport interface properly into IEEE1284_PH_REV_IDLE phase at

c660629059 [PATCH] parport: buffer overflow fix
Fix potential buffer overflow in case the device ID did not end in semicolon.
Also might fail to negotiate back to IEEE1284_MODE_COMPAT in case of failure.
parport_device_id did not return what Documentation/parport-lowlevel.txt said,
so I changed it to match it.

Determining device ID length is overly complicated, but Tim Waugh recalled on
linux-parport seeing some buggy device that might need it.

39ee059aff [PATCH] fuse: check file type in lookup
Previously invalid types were quietly changed to regular files, but at
revalidation the inode was changed to bad.  This was rather inconsistent
behavior.

Now check if the type is valid on initial lookup, and return -EIO if not.

6ad84acab9 [PATCH] fuse: ensure progress in read and write
In direct_io mode, send at least one page per reqest.  Previously it was
possible that reqests with zero data were sent, and hence the read/write
didn't make any progress, resulting in an infinite (though interruptible)
loop.

3ec870d524 [PATCH] fuse: make maximum write data configurable
Make the maximum size of write data configurable by the filesystem.  The
previous fixed 4096 limit only worked on architectures where the page size is
less or equal to this.  This change make writing work on other architectures
too, and also lets the filesystem receive bigger write requests in direct_io
mode.

Normal writes which go through the page cache are still limited to a page
sized chunk per request.

1d3d752b47 [PATCH] fuse: clean up request size limit checking
Change the way a too large request is handled.  Until now in this case the
device read returned -EINVAL and the operation returned -EIO.

Make it more flexibible by not returning -EINVAL from the read, but restarting
it instead.

Also remove the fixed limit on setxattr data and let the filesystem provide as
large a read buffer as it needs to handle the extended attribute data.

The symbolic link length is already checked by VFS to be less than PATH_MAX,
so the extra check against FUSE_SYMLINK_MAX is not needed.

The check in fuse_create_open() against FUSE_NAME_MAX is not needed, since the
dentry has already been looked up, and hence the name already checked.

8cbdf1e6f6 [PATCH] fuse: support caching negative dentries
Add support for caching negative dentries.

Up till now, ->d_revalidate() always forced a new lookup on these.  Now let
the lookup method return a zero node ID (not used for anything else) meaning a
negative entry, but with a positive cache timeout.  The old way of signaling
negative entry (replying ENOENT) still works.

Userspace should check the ABI minor version to see whether sending a zero ID
is allowed by the kernel or not.

8129ee1642 [PATCH] s390: qdio V=V pass-through
New feature V=V qdio pass-through.

QDIO and HiperSockets processing in z/VM V=V guest environments (as well as
V=R with z/VM running in LPAR mode) requires shadowing of all QDIO
architecture queue elements.  Especially the shadowing of SBALs and SLSBs
structures in the hypervisor, and the need to issue SIGA SYNC operations to
observe state changes, eventually causes significant CPU processing overhead
in the hypervisor.

The QDIO pass-through support for V=V guests avoids the shadowing of SBALs and
SLSBs.  This significantly reduces the hypervisor overhead for QDIO based I/O.

973bd99375 [PATCH] s390: atomic primitives
Hugh Dickins <hugh@veritas.com>

Fix the broken atomic_cmpxchg primitive.  Add atomic_sub_and_test,
atomic64_sub_return, atomic64_sub_and_test, atomic64_cmpxchg,
atomic64_add_unless and atomic64_inc_not_zero.  Replace old style
atomic_compare_and_swap by atomic_cmpxchg.  Shorten the whole header by
defining most primitives with the two inline functions atomic_add_return and
atomic_sub_return.

In addition this patch contains the s390 related fixes of Hugh's "mm: fill
arch atomic64 gaps" patch.
