[PATCH v2 3/4] migration: Fix cache_init()'s "Failed to allocate" error messages
Posted by Markus Armbruster 5 years ago
cache_init() attempts to handle allocation failure..  The two error
messages are garbage, as untested error messages commonly are:

    Parameter 'cache size' expects Failed to allocate cache
    Parameter 'cache size' expects Failed to allocate page cache

Fix them to just

    Failed to allocate cache
    Failed to allocate page cache

Typo.  Perhaps the maintainer can take care of it.

Yeh I can try and remember to take it out on the merge.
