| * [CIFS] Fix memory overwrite when saving nativeFileSystem field during mountSteve French2009-03-18
| | | | | | | | | | | | | | | | | | | | | | CIFS can allocate a few bytes to little for the nativeFileSystem field during tree connect response processing during mount. This can result in a "Redzone overwritten" message to be logged.

| * [CIFS] work around bug in Samba server handling for posix openSteve French2009-03-11
| | | | | | | | | | | | | | | | | | | | | | Samba server (version 3.3.1 and earlier, and 3.2.8 and earlier) incorrectly required the O_CREAT flag on posix open (even when a file was not being created). This disables posix open (create is still ok) after the first attempt returns EINVAL (and logs an error, once, recommending that they update their server).

| * cifs: fix buffer format byte on NT Rename/hardlinkJeff Layton2009-03-11
| | | | | | | | | | | | | | | | | | | | | | | | | | Discovered at Connnectathon 2009... The buffer format byte and the pad are transposed in NT_RENAME calls (which are used to set hardlinks). Most servers seem to ignore this fact, but NetApp filers throw back an error due to this problem. This patch fixes it.

| * [CIFS] Add definitions for remoteably fsctl callsSteve French2009-03-11
| | | | | | | | | | | | | | | | | | There are about 60 fsctl calls which Windows claims would be able to be sent remotely and handled by the server. This adds the #defines for them. A few of them look immediately useful, but need to also add the structure definitions for them so they can be sent as SMBs. Signed-off-by: Steve French <sfrench@us.ibm.com>

| * [CIFS] Add new nostrictsync cifs mount option to avoid slow SMB flushSteve French2009-03-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If this mount option is set, when an application does an fsync call then the cifs client does not send an SMB Flush to the server (to force the server to write all dirty data for this file immediately to disk), although cifs still sends all dirty (cached) file data to the server and waits for the server to respond to the write write. Since SMB Flush can be very slow, and some servers may be reliable enough (to risk delaying slightly flushing the data to disk on the server), turning on this option may be useful to improve performance for applications that fsync too much, at a small risk of server crash. If this mount option is not set, by default cifs will send an SMB flush request (and wait for a response) on every fsync call. Signed-off-by: Steve French <sfrench@us.ibm.com>

| * [CIFS] Send SMB flush in cifs_fsyncSteve French2009-03-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In contrast to the now-obsolete smbfs, cifs does not send SMB_COM_FLUSH in response to an explicit fsync(2) to guarantee that all volatile data is written to stable storage on the server side, provided the server honors the request (which, to my knowledge, is true for Windows and Samba with 'strict sync' enabled). This patch modifies the cifs_fsync implementation to restore the fsync-behavior of smbfs by triggering SMB_COM_FLUSH after sending outstanding data on the client side to the server.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | We don't have to start a transaction in writepage() when all the blocks are a properly allocated. Even in ordered mode either the data has been written via write() and they are thus already added to transaction's list or the data was written via mmap and then it's random in which transaction they get written anyway.

This prevents us from attempting to use dubious multi_count values ad infinitum. Reset dev->multi_count to zero and reprobe it each time through this routine, as it can change on device reset. Also ensure that the reported "maximum" value is valid and is a power of two, and that the reported "count" value is valid and also a power of two. And that the "count" value is not greater than the "maximum" value. Signed-off-by: Mark Lord <mlord@pobox.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

Add a quirk that enables blink mode for the LED while NCQ is enabled on any port of a SoC host controller. Normal LED function is restored when NCQ is not enabled on any port.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add IRQ coalescing to sata_mv (off by default). This feature can reduce total interrupt overhead for RAID setups in some situations, by deferring the interrupt signal until one or both of: a) a specified io_count (completed SATA commands) is achieved, or b) a specified time interval elapses after an IO completion. For now, module parameters are used to set the irq_coalescing_io_count and irq_coalescing_usecs (timeout) globally. These may eventually be supplemented with sysfs attributes, so that thresholds can be set on-the-fly and on a per-chip (or even per-host_controller) basis.

When using command issue via the "mv_qc_issue_fis()" mechanism, the initial ATA_BUSY bit does not show in the ATA status (shadow) register. This can confuse libata!

This might be needed on machines if the BIOS turns intx off during boot. However, there's no evidence of such behavior for ahci and the only such case seems to be ICH5 PATA according to ata_piix.
