* git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging-2.6: (43 commits) staging: slicoss: update README otus/zdusb.c: additional USB idnetifier Staging: go7007: fix build issues Staging: sxg: Fix leaks and checksum errors in transmit code path Staging: sxg: Fix sleep in atomic context warning while loading driver Staging: sxg: Use correct queue_id for transmitting non-TCP packets Staging: sxg: Fire watchdog timer at end of open routine to change the link Staging: Pohmelfs: Add load balancing between network states with the same priority. Staging: Pohmelfs: Added IO permissions and priorities. Staging: Pohmelfs: Added ->show_stats() callback. Staging: Pohmelfs: Drop ftrans debugging code. Staging: Pohmelfs: Use wait_on_page_timeout when waiting for remote directory sync instead of hardcoded 25 seconds. Staging: Pohmelfs: Reduce debugging noise about non-existing objects. Staging: Pohmelfs: Sync fs before killing it, since dentry cache is shrunk before writeback is invoked via generic_shutdown_super() Staging: Pohmelfs: Extend remount option. Staging: Pohmelfs: Set NETFS_INODE_REMOTE_SYNCED and clear NETFS_INODE_OWNED bits in the root inode. Staging: Pohmelfs: Added 'need_lock' variable into debug print. Staging: Pohmelfs: Disable read lock in pohmelfs_getattr(). Staging: Pohmelfs: Move parent lock to the place where we really have to send a lookup request to the server. Staging: pohmelfs: Populate dentry cache when receiving the new readdir entry. ...
