D11290: [UDevManager] Already filter for subsystem before querying

[Kai Uwe Broulik]

broulik added a comment.


  It brings the number of sys calls from 28000 down to 860 here using the first grep command in the comment, could have helped somewhat I guess but the second command is completely bogus for me. needs further investigation. It does give a significant speedup which is already worth it ;)
