This patch simply adds a newline character at end-of-file to those files in Documentation/ that currently lack one. This is done for a few different reasons: A) It's rather annoying when you do "cat some_file.txt" that your prompt/cursor ends up at the end of the last line of output rather than on a new line. B) Some tools that process files line-by-line may get confused by the lack of a newline on the last line. C) The "\ No newline at end of file" line in diffs annoys me for some reason. So, let's just add the missing newline once and for all. Signed-off-by: Jesper Juhl <jj@chaosbits.net> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

What: /sys/block/zram/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/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/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/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/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/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/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/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/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/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/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/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
