Now that the roundup macro is sane, it can't be used in structure
definitions, or the build breaks.. For now, create a "broken_roundup()"
macro to get everything building again, but in the end, fixing these
structures to use a proper size value is the correct thing to do.

The way network devices are reference counted does not include poking
around in the reference count itself. This breaks when the reference

Commit 3e4d3af501cc ("mm: stack based kmap_atomic()") overlooked the
fact that parisc uses kmap as a coherence mechanism, so even though we
have no highmem, we do need to supply our own versions of kmap (and
atomic). This patch converts the parisc kmap to the form which is
needed to keep it compiling (it's a simple prototype and name change).

Today's git tree fails to build on !CONFIG_BLOCK, due to upstream commit
367a51a33902 ("fs: Add FITRIM ioctl"):

include/linux/fs.h:36: error: expected specifier-qualifier-list before ‘uint64_t’
include/linux/fs.h:36: error: expected specifier-qualifier-list before ‘uint64_t’
The commit adds uint64_t type usage to fs.h, but linux/types.h is not included
explicitly - it's only included implicitly via linux/blk_types.h, and there only if
CONFIG_BLOCK is enabled.
Add the explicit #include to fix this.

SYNOPSIS
size[4] Tfsync tag[2] fid[4] datasync[4]
size[4] Rfsync tag[2]
DESCRIPTION
The Tfsync transaction transfers ("flushes") all modified in-core data of
file identified by fid to the disk device (or other permanent storage
device) where that file resides.
If datasync flag is specified data will be fleshed but does not flush
modified metadata unless that metadata is needed in order to allow a
subsequent data retrieval to be correctly handled.

P9_LOCK_SUCCESS - Request was successful
P9_LOCK_BLOCKED - A conflicting lock is held by another process
P9_LOCK_ERROR - Error while processing the lock request
P9_LOCK_GRACE - Server is in grace period, it can't accept new lock

The presence of v9fs_direct_IO() in the address space ops vector
allowes open() O_DIRECT flags which would have failed otherwise.
In the non-cached mode, we shunt off direct read and write requests before
the VFS gets them, so this method should never be called.
Direct IO is not 'yet' supported in the cached mode. Hence when
this routine is called through generic_file_aio_read(), the read/write fails
with an error.

so that the newly created directory inherits the gid from parent

Current 9p client file write code does not check for RLIMIT_FSIZE resource.
This bug was found by running LTP test case for setrlimit. This bug is fixed
by calling generic_write_checks before sending the write request to the
server.
Without this patch: the write function is allowed to write above the
RLIMIT_FSIZE set by user.
With this patch: the write function checks for RLIMIT_SIZE and writes upto
the size limit.
