*	[S390] cio: Add chsc subchannel driver.	Cornelia Huck	2008-07-14	1	-1/+1
\| \| \| \| \| \| \| \| \| \| \| \| \|	This patch adds a driver for subchannels of type chsc. A device /dev/chsc is created which may be used to issue ioctls to: - obtain information about the machine's I/O configuration - dynamically change the machine's I/O configuration via asynchronous chsc commands Signed-off-by: Cornelia Huck <cornelia.huck@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com> Signed-off-by: Heiko Carstens <heiko.carstens@de.ibm.com>
*	[S390] cio: replace subchannel evaluation queue with bitmap	Peter Oberparleiter	2007-04-27	1	-0/+25
	Use a bitmap for indicating which subchannels require evaluation instead of allocating memory for each evaluation request. This approach reduces memory consumption during recovery in case of massive evaluation request occurrence and removes the need for memory allocation failure handling.
