Revision b538b8ce76f69f7fa225bc0817bbb361b877ea23 authored by David Spinadel on 13 May 2014, 11:29:36 UTC, committed by Emmanuel Grumbach on 13 May 2014, 12:05:32 UTC
Prevent sched scan while not idle (including during association or in AP mode) instead of while associated only. This fixes my previous commit which was incomplete: commit bd5e4744a6ca64299b57a2682c720d00a475a734 Author: David Spinadel <david.spinadel@intel.com> Date: Thu Apr 24 13:15:29 2014 +0300 iwlwifi: mvm: do no sched scan while associated Currently the FW doesn't support sched scan while associated, Prevent it.

menuconfig BLOCK
bool "Enable the block layer" if EXPERT
default y
help
Provide block layer support for the kernel.
Disable this option to remove the block layer support from the
kernel. This may be useful for embedded devices.
If this option is disabled:
- block device files will become unusable
- some filesystems (such as ext3) will become unavailable.
Also, SCSI character devices and USB storage will be disabled since
they make use of various block layer definitions and facilities.
Say Y here unless you know you really don't want to mount disks and
suchlike.
if BLOCK
config LBDAF
bool "Support for large (2TB+) block devices and files"
depends on !64BIT
default y
help
Enable block devices or files of size 2TB and larger.
This option is required to support the full capacity of large
(2TB+) block devices, including RAID, disk, Network Block Device,
Logical Volume Manager (LVM) and loopback.
This option also enables support for single files larger than
2TB.
The ext4 filesystem requires that this feature be enabled in
order to support filesystems that have the huge_file feature
enabled. Otherwise, it will refuse to mount in the read-write
mode any filesystems that use the huge_file feature, which is
enabled by default by mke2fs.ext4.
The GFS2 filesystem also requires this feature.
If unsure, say Y.
config BLK_DEV_BSG
bool "Block layer SG support v4"
default y
help
Saying Y here will enable generic SG (SCSI generic) v4 support
for any block device.
Unlike SG v3 (aka block/scsi_ioctl.c drivers/scsi/sg.c), SG v4
can handle complicated SCSI commands: tagged variable length cdbs
with bidirectional data transfers and generic request/response
protocols (e.g. Task Management Functions and SMP in Serial
Attached SCSI).
This option is required by recent UDEV versions to properly
access device serial numbers, etc.
If unsure, say Y.
config BLK_DEV_BSGLIB
bool "Block layer SG support v4 helper lib"
default n
select BLK_DEV_BSG
help
Subsystems will normally enable this if needed. Users will not
normally need to manually enable this.
If unsure, say N.
config BLK_DEV_INTEGRITY
bool "Block layer data integrity support"
---help---
Some storage devices allow extra information to be
stored/retrieved to help protect the data. The block layer
data integrity option provides hooks which can be used by
filesystems to ensure better data integrity.
Say yes here if you have a storage device that provides the
T10/SCSI Data Integrity Field or the T13/ATA External Path
Protection. If in doubt, say N.
config BLK_DEV_THROTTLING
bool "Block layer bio throttling support"
depends on BLK_CGROUP=y
default n
---help---
Block layer bio throttling support. It can be used to limit
the IO rate to a device. IO rate policies are per cgroup and
one needs to mount and use blkio cgroup controller for creating
cgroups and specifying per device IO rate policies.
See Documentation/cgroups/blkio-controller.txt for more information.
config BLK_CMDLINE_PARSER
bool "Block device command line partition parser"
default n
---help---
Enabling this option allows you to specify the partition layout from
the kernel boot args. This is typically of use for embedded devices
which don't otherwise have any standardized method for listing the
partitions on a block device.
See Documentation/block/cmdline-partition.txt for more information.
