* i2c-stub: Mention the existence of an helper scriptJean Delvare2008-01-27

* i2c-pasemi: use i2c_add_numbered_adapter()Olof Johansson2008-01-27
| | | | | | | | | | | | | Use numbered adapter registration to always have the same hardware bus show up at the same number. PWRficient 1682M has three buses, they are all on the same PCI device but different functions. So do the simple thing and register them based on function number. Future products, if having a different number of busses, are expected to have similar behaviour w.r.t. device/function layout.

* i2c-nforce2: The nForce2 can do block transactionsJean Delvare2008-01-27

| * [CIFS] use krb5 session key from first SMB session after a NegProtJeff Layton2007-12-30
| | | | | | | | | | | | | | | | | | Currently, any new kerberos SMB session overwrites the server's session key. The session key should only be set by the first SMB session set up on the socket.

| * [CIFS] redo existing session setup if needed in cifs_mountJeff Layton2007-12-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When cifs_mount finds an existing SMB session that it can use for a new mount, it does not check to see whether that session is in need of being reconnected. An easy way to reproduce: 1) mount //server/share1 2) watch /proc/fs/cifs/DebugData for the share to go DISCONNECTED 3) mount //server/share2 with same creds as in step 1. The second mount will fail because CIFSTCon returned -EAGAIN. If you do an operation in share1 and then reattempt the mount it will work (since the session is reestablished). The following patch fixes this by having cifs_mount check the status of the session when it picks an existing session and calling cifs_setup_session on it again if it's in need of reconnection. Thanks to Wojciech Pilorz for the initial bug report. Signed-off-by: Jeff Layton <jlayton@tupile.poochiereds.net> Signed-off-by: Steve French <sfrench@us.ibm.com>

It was cleared and restored during ioctl requests but there was no synchronization with other requests. So, other requests could execute with the altered ->io_32bit setting or updated drive->io_32bit could be overwritten by ide_taskfile_ioctl(). This patch adds IDE_TFLAG_IO_16BIT flag to indicate to ide_pio_datablock() that 16-bit I/O is needed regardless of drive->io_32bit settting.
