2010-10-25cifs: wait for writeback to complete in cifs_flushJeff Layton
The f_op->flush operation is the last chance to return a writeback related error when closing a file. Ensure that we don't miss reporting any errors by waiting for writeback to complete in cifs_flush before proceeding. There's no reason to do this when the file isn't open for write however.

2010-10-25cifs: convert cifsFileInfo->count to non-atomic counterJeff Layton
The count for cifsFileInfo is currently an atomic, but that just adds complexity for little value. We generally need to hold cifs_file_list_lock to traverse the lists anyway so we might as well make this counter non-atomic and simply use the cifs_file_list_lock to protect it.

2010-10-25jffs2: Dynamically choose inocache hash sizeDaniel Drake
When JFFS2 is used for large volumes, the mount times are quite long. Increasing the hash size provides a significant speed boost on the OLPC XO-1 laptop. Add logic that dynamically selects a hash size based on the size of the medium. A 64mb medium will result in a hash size of 128, and a 512mb medium will result in a hash size of 1024.

2010-10-24NFSv4.1: pnfs: add LAYOUTGET and GETDEVICEINFO infrastructureAndy Adamson
Add the ability to actually send LAYOUTGET and GETDEVICEINFO. This also adds in the machinery to handle layout state and the deviceid cache. Note that GETDEVICEINFO is not called directly by the generic layer. Instead it is called by the drivers while parsing the LAYOUTGET opaque data in response to an unknown device id embedded therein. RFC 5661 only encodes device ids within the driver-specific opaque data.

2010-10-24NFS: client needs to maintain list of inodes with active layoutsAndy Adamson
In particular, server reboot will invalidate all layouts. Note that in order to have an active layout, we must get a successful response from the server. To avoid adding that machinery, this patch just includes a stub that fakes up a successful return. Since the layout is never referenced for io, this is not a problem.

2010-10-24Revalidate caches on lockRicardo Labiaga
Instead of blindly zapping the caches, attempt to revalidate them if the server has indicated that it uses high resolution timestamps. NFSv4 should be able to always revalidate the cache since the protocol requires the update of the change attribute on modification of the data. In reality, there are servers (the Linux NFS server for example) that do not obey this requirement and use ctime as the basis for change attribute. Long term, the server needs to be fixed. At this time, and to be on the safe side, continue zapping caches if the server indicates that it does not have a high resolution timestamp.

By requsting more attributes during a readdir, we can mimic the readdir plus operation that was in NFSv3.

This patch adds the readdir cache array and functions to retreive the array stored on a cache page, clear the array by freeing allocated memory, add an entry to the array, and search the array for a given cookie. It then modifies readdir to make use of the new cache array. With the new cache array method, we no longer need some of this code. Finally, nfs_llseek_dir() will set file->f_pos to a value greater than 0 and desc->dir_cookie to zero. When we see this, readdir needs to find the file at position file->f_pos from the start of the directory.

2010-10-23Revert "tty: Add a new file /proc/tty/consoles"Linus Torvalds
This reverts commit f4a3e0bceb57466c31757f25e4e0ed108d1299ec. Jiri Sladby points out that the tty structure we're using may already be gone, and Al Viro doesn't hold back in complaining about the random loading of 'filp->private_data' which doesn't have to be a pointer at all, nor does checking the magic field for TTY_MAGIC prove anything. Belated review by Al: "a) global variable depending on stdin of the last opener? Affecting output of read(2)? Really? b) iterator is broken; list should be locked in ->start(), unlocked in ->stop() and *NOT* unlocked/relocked in ->next() c) ->show() ought to do nothing in case of ->device == NULL, instead of skipping those in ->next()/->start() d) regardless of the merits of the bright idea about asterisk at that line in output *and* regardless of (a), the implementation is not only atrociously ugly, it's actually very likely to be a roothole. Verifying that Cthulhu knows what number happens to be address of a tty_struct by blindly dereferencing memory at that address... Ouch. Please revert that crap." And Christoph pipes in and NAK's the approach of walking fd tables etc too. So it's pretty unanimous.

2010-10-22ocfs2: drop the BLKDEV_IFL_WAIT flagLinus Torvalds
Commit dd3932eddf42 ("block: remove BLKDEV_IFL_WAIT") had removed the flag argument to blkdev_issue_flush(), but the ocfs2 merge brought in a new one. It didn't cause a merge conflict, so the merges silently worked out fine, but the result didn't actually compile. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
