If recovery is triggered in presence of pending asynchronous deliveries of storage blocks we do a forced cleanup after the corresponding tasklets are completely stopped and trigger appropriate notifications for the correspondingerror state. Signed-off-by:

In case there are no system resources to run a recovery we have to clear recovery bitmasks so a further automatic or manual driven recovery can fix up the device. Signed-off-by:

The NETIUCV device driver allows to connect a Linux guest on z/VM to another z/VM guest based on the z/VM communication facility IUCV. Multiple output paths to different guests are possible, as well as multiple input paths from different guests. With this feature, you can configure multiple point-to-point NETIUCV interfaces between your Linux on System z instance and another z/VM guest. Signed-off-by:

module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version. (Thanks to Joe Perches for suggesting coccinelle for 0/1 -> true/false). Cc: "David S.

This patch adds the ethtool callbacks necessary to change the rss indirection table from userspace. Should the number of interrupts change (e.g. across a close / open call, or through a reset) and any one of the indirection table values fall out-of-range, the driver will reset the indirection table to a default layout. [Integrated many suggestions made by Ben Hutchings.] Changes since v3 * Removed TG3_FLAG_SUPPORT_MSIX checks at the start of tg3_get_rxfh_indir() and tg3_set_rxfh_indir(). Signed-off-by:

bnx2-mips-06-6.2.3 and bnx2-mips-09-6.2.1.b New firmware fixes iSCSI problems with some LeftHand targets that don't set TTT=0xffffffff for Data-In according to spec. Firmware generates exception warnings for this condition and becomes very slow. This is fixed by suppressing these warnings when using default error mask. Signed-off-by:

Lancer does not have HW registers to indicate the EQ causing the INTx interrupt. As a result EQE entries of one EQ may be consumed when interrupt is caused by another EQ. Fix this by arming CQs at the end of NAPI poll routine to regenerate the EQEs. Signed-off-by:

New FW can give clues to driver regarding default port type and whether or not we should default to link sensing on the port. 2 bits are added to QUERY_PORT command: 1. suggested_type: This bit gives a hint whether the default port type should be IB or Ethernet. The driver will use this hint in case the user didn't specify explicitly the link layer type he wants to set. 2. default_sense: If this bit is set, we would sense the port type on start-up and default the port to link sensing Signed-off-by:

We can't scan the proto_list to initialize sock cgroups, as it holds a rwlock, and we also want to keep the code generic enough to avoid calling the initialization functions of protocols directly, Convert proto_list_lock into a mutex, so we can sleep and do the necessary allocations. This lock is seldom taken, so there shouldn't be any performance penalties associated with that Signed-off-by:
