Merge git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging-2.6
* git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging-2.6: (841 commits) Staging: brcm80211: fix usage of roundup in structures Staging: bcm: fix up network device reference counting Staging: keucr: fix up US_ macro change staging: brcm80211: brcmfmac: Removed codeversion from firmware filenames. staging: brcm80211: Remove unnecessary header files. staging: brcm80211: Remove unnecessary includes from bcmutils.c staging: brcm80211: Removed unnecessary pktsetprio() function. Staging: brcm80211: remove typedefs.h Staging: brcm80211: remove uintptr typedef usage Staging: hv: remove struct vmbus_channel_interface Staging: hv: remove Open from struct vmbus_channel_interface Staging: hv: storvsc: call vmbus_open directly Staging: hv: netvsc: call vmbus_open directly Staging: hv: channel: export vmbus_open to modules Staging: hv: remove Close from struct vmbus_channel_interface Staging: hv: netvsc: call vmbus_close directly Staging: hv: storvsc: call vmbus_close directly Staging: hv: channel: export vmbus_close to modules Staging: hv: remove SendPacket from struct vmbus_channel_interface Staging: hv: storvsc: call vmbus_sendpacket directly ... Fix up conflicts in drivers/staging/cx25821/cx25821-audio-upstream.c drivers/staging/cx25821/cx25821-audio.h due to warring whitespace cleanups (neither of which were all that great)

+What: /sys/block/zram<id>/disksize
+Date: August 2010
+Contact: Nitin Gupta <ngupta@vflare.org>
+Description:
+ The disksize file is read-write and specifies the disk size
+ which represents the limit on the *uncompressed* worth of data
+ that can be stored in this disk.
+
+What: /sys/block/zram<id>/initstate
+Date: August 2010
+Contact: Nitin Gupta <ngupta@vflare.org>
+Description:
+ The disksize file is read-only and shows the initialization
+ state of the device.
+
+What: /sys/block/zram<id>/reset
+Date: August 2010
+Contact: Nitin Gupta <ngupta@vflare.org>
+Description:
+ The disksize file is write-only and allows resetting the
+ device. The reset operation frees all the memory assocaited
+ with this device.

+What: /sys/block/zram<id>/num_reads
+Date: August 2010
+Contact: Nitin Gupta <ngupta@vflare.org>
+Description:
+ The num_reads file is read-only and specifies the number of
+ reads (failed or successful) done on this device.

+What: /sys/block/zram<id>/num_writes
+Date: August 2010
+Contact: Nitin Gupta <ngupta@vflare.org>
+Description:
+ The num_writes file is read-only and specifies the number of
+ writes (failed or successful) done on this device.

+What: /sys/block/zram<id>/invalid_io
+Date: August 2010
+Contact: Nitin Gupta <ngupta@vflare.org>
+Description:
+ The invalid_io file is read-only and specifies the number of
+ non-page-size-aligned I/O requests issued to this device.
+
+What: /sys/block/zram<id>/notify_free
+Date: August 2010
+Contact: Nitin Gupta <ngupta@vflare.org>
+Description:
+ The notify_free file is read-only and specifies the number of
+ swap slot free notifications received by this device. These
+ notifications are send to a swap block device when a swap slot
+ is freed. This statistic is applicable only when this disk is
+ being used as a swap disk.
+
+What: /sys/block/zram<id>/discard
+Date: August 2010
+Contact: Nitin Gupta <ngupta@vflare.org>
+Description:
+ The discard file is read-only and specifies the number of
+ discard requests received by this device. These requests
+ provide information to block device regarding blocks which are
+ no longer used by filesystem.
+
+What: /sys/block/zram<id>/zero_pages
+Date: August 2010
+Contact: Nitin Gupta <ngupta@vflare.org>
+Description:
+ The zero_pages file is read-only and specifies number of zero
+ filled pages written to this disk. No memory is allocated for
+ such pages.
+
+What: /sys/block/zram<id>/orig_data_size
+Date: August 2010
+Contact: Nitin Gupta <ngupta@vflare.org>
+Description:
+ The orig_data_size file is read-only and specifies uncompressed
+ size of data stored in this disk. This excludes zero-filled
+ pages (zero_pages) since no memory is allocated for them.
+ Unit: bytes

+What: /sys/block/zram<id>/compr_data_size
+Date: August 2010
+Contact: Nitin Gupta <ngupta@vflare.org>
+Description:
+ The compr_data_size file is read-only and specifies compressed
+ size of data stored in this disk. So, compression ratio can be
+ calculated using orig_data_size and this statistic.
+ Unit: bytes
+
+What: /sys/block/zram<id>/mem_used_total
+Date: August 2010
+Contact: Nitin Gupta <ngupta@vflare.org>
+Description:
+ The mem_used_total file is read-only and specifies the amount
+ of memory, including allocator fragmentation and metadata
+ overhead, allocated for this disk. So, allocator space
+ efficiency can be calculated using compr_data_size and this
+ statistic.
+ Unit: bytes \ No newline at end of file
