[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Minios-devel] [UNIKRAFT PATCH v4 11/16] include/uk: prefix functions in bitmap.h and bitopts.h
This patch adds prefix to majority of the macros/functions. For the
sake of tractability, patch touches only functions either not
used (yet) or used no more then a couple of times
