* 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.

POHMELFS is capable of full data channel encryption and/or strong crypto hashing.
One can select any kernel supported cipher, encryption mode, hash type and operation mode

Usage examples.
Add (or remove if it already exists) server server1.net:1025 into the working set with index $idx
Add server server1.net:1025 into the working set with index $idx
with appropriate hash algorithm and key file and cipher algorithm, mode and key file:
$cfg -a server1.net -p 1025 -i $idx -K $hash_key -k $cipher_key
$cfg A add -a server1.net -p 1025 -i $idx -K $hash_key -k $cipher_key
Mount filesystem with given index $idx to /mnt mountpoint.
Client will connect to all servers specified in the working set via previous command:
mount -t pohmel -o idx=$idx q /mnt
One can add or remove servers from working set after mounting too.
Change permissions to read-only (-I 1 option, '-I 2' - write-only, 3 - rw):
$cfg A modify -a server1.net -p 1025 -i $idx -I 1
Change IO priority to 123 (node with the highest priority gets read requests).
$cfg A modify -a server1.net -p 1025 -i $idx -P 123
One can check currect status of all connections in the mountstats file:
# cat /proc/$PID/mountstats

- move firmware loading to request_firmware()
- remove direct memory access of structures
- any remaining sparse and checkpatch.pl warnings
- any netdev recommended changes
- use net_device_ops
- use dev->stats rather than adapter->stats
- don't cast netdev_priv it is already void
- use compare_ether_addr
- GET RID OF MACROS
- work on all architectures
- without CONFIG_X86_64 confusion
- do 64 bit correctly
- don't depend on order of union
- get rid of ASSERT(), use BUG() instead but only where necessary
looks like most aren't really useful
- no new SIOCDEVPRIVATE ioctl allowed
- don't use module_param for configuring interrupt mitigation
use ethtool instead
- reorder code to elminate use of forward declarations
- don't keep private linked list of drivers.
- remove all the gratiutous debug infrastructure
- use PCI_DEVICE()
- do ethtool correctly using ethtool_ops
- NAPI?
- wasted overhead of extra stats
- state variables for things that are
easily availble and shouldn't be kept in card structure, cardnum, ...
slotnumber, events, ...
- get rid of slic_spinlock wrapper
- volatile == bad design => bad code
- locking too fine grained, not designed just throw more locks
at problem
Please send patches to:
