|
Now a cache set only has a single cache, therefore "bcache make" should
|
||
|
|
permit only one cache device to be specified for a cache set.
|
||
|
|
|
||
|
|
This patch checks if more than one cache devices are specified by "-C"
|
||
|
|
an error message "Please specify only one cache device" will be printed
|
||
|
|
and bcache exits with usage information.
