Commit Message

SeongJae Park Feb. 15, 2022, 6:45 p.m. UTC
DAMON has a set of callback functions called monitoring primitives and
let it can be configured with various implementations for easy extension
for different address spaces and usages.  However, the word 'primitive'
is not so explicit.  Meanwhile, many other structs resembles similar
purpose calls themselves 'operations'.  To make the code easier to be
understood, this commit renames 'damon_primitives' to 'damon_operations'
before it is too late to rename.
