Subject: [PATCH] libmultipath: check the overrides pctable for path variables
|
|
|
7805a0 |
|
|
|
7805a0 |
Paths will now also check the pctable when checking for attribtes that
|
|
|
7805a0 |
exists in both the overrides section and the protocol subsection. Values
|
|
|
7805a0 |
in a matching pcentry will be used in preference to values in the
|
|
|
7805a0 |
overrides hwentry.
