It depends on tristate I2C and it's trivial to make modular. The current Kconfig allows I2C=m, I2C_ACORN=y, which doesn't work at all; alternatives are dependency on I2C=y and making I2C_ACORN itself a tristate. The latter is the right thing to do... Signed-off-by:

During reorganization, the mount time debug option was removed in favor of module-load-time parameters. However, the mount time option is still a useful for feature during debug and for user-fault isolation when the module is compiled into the kernel. Signed-off-by: -

This patchset moves non-filesystem interfaces of v9fs from fs/9p to net/9p. It moves the transport, packet marshalling and connection layers to net/9p leaving only the VFS related files in fs/9p. This work is being done in preparation for in-kernel 9p servers as well as alternate 9p clients (other than VFS). Signed-off-by:

XFS filestreams functionality uses radix trees and the preload functions. XFS can be built as a module and hence we need radix_tree_preload() exported. radix_tree_preload_end() is a static inline, so it doesn't need exporting. Signed-Off-By:

* 32bit struct xfs_fsop_bulkreq has different size and layout of members, no matter the alignment. Move the code out of the #else branch (why was it there in the first place?). Define _32 variants of the ioctl constants. * 32bit struct xfs_bstat is different because of time_t and on i386 because of different padding. Make xfs_bulkstat_one() accept a custom "output formatter" in the private_data argument which takes care of the xfs_bulkstat_one_compat() that takes care of the different layout in the compat case. * i386 struct xfs_inogrp has different padding. Add a similar "output formatter" mecanism to xfs_inumbers(). SGI-PV: 967354 SGI-Modid: xfs-linux-melb:xfs-kern:29102a Signed-off-by:

Avoid using a special "zero inode" as the parent of the quota inode as this can confuse the filestreams code into thinking the quota inode has a parent. We do not want the quota inode to follow filestreams allocation rules, so pass a NULL as the parent inode and detect this condition when doing stream associations.

In media spaces, video is often stored in a frame-per-file format. When dealing with uncompressed realtime HD video streams in this format, it is crucial that files do not get fragmented and that multiple files a placed contiguously on disk. When multiple streams are being ingested and played out at the same time, it is critical that the filesystem does not cross the streams and interleave them together as this creates seek and readahead cache miss latency and prevents both ingest and playout from meeting frame rate targets. This patch set creates a "stream of files" concept into the allocator to place all the data from a single stream contiguously on disk so that RAID array readahead can be used effectively. Each additional stream gets placed in different allocation groups within the filesystem, thereby ensuring that we don't cross any streams. When an AG fills up, we select a new AG for the stream that is not in use. The core of the functionality is the stream tracking - each inode that we create in a directory needs to be associated with the directories' stream. Hence every time we create a file, we look up the directories' stream object and associate the new file with that object. Once we have a stream object for a file, we use the AG that the stream object point to for allocations. If we can't allocate in that AG (e.g. it is full) we move the entire stream to another AG. Other inodes in the same stream are moved to the new AG on their next allocation (i.e. lazy update). Stream objects are kept in a cache and hold a reference on the inode. Hence the inode cannot be reclaimed while there is an outstanding stream reference. This means that on unlink we need to remove the stream association and we also need to flush all the associations on certain events that want to reclaim all unreferenced inodes (e.g. filesystem freeze).

A check for file_count is always a bad idea. Linux has the ->release method to deal with cleanups on last close and ->flush is only for the very rare case where we want to perform an operation on every drop of a reference to a file struct. This patch gets rid of vop_close and surrounding code in favour of simply doing the page flushing from ->release. SGI-PV: 966562 SGI-Modid: xfs-linux-melb:xfs-kern:28952a Signed-off-by:

The remount readonly path can fail to writeback properly because we still have active transactions after calling xfs_quiesce_fs(). Further investigation shows that this path is broken in the same ways that the xfs freeze path was broken so fix it the same way.
