Subject: [PATCH 111/217] cxl/memdev: Cleanup memdev filter
|
|
|
2eb93d |
|
|
|
2eb93d |
util_cxl_memdev_filter() already handles the difference between 'mem%d',
|
|
|
2eb93d |
'%d', and 'all' for the identifier format. Drop the duplicate / incomplete
|
|
|
2eb93d |
format checking.
|
|
|
2eb93d |
|
|
|
2eb93d |
If the checking for bad formats was dropped too then this command could
|
|
|
2eb93d |
support "0,1,2" syntax in addition to "0 1 2" like 'cxl list'. However, it is
|
|
|
2eb93d |
not clear that's worthwhile since 'list' is ok to be imprecise, but memdev
|
|
|
2eb93d |
commands need to be stricter.
