...esn't > block all learning or requires a lock. At the time of writing v2, this seemed difficult because we want to test multiple bits and increment a counter, but remembering that clear_bit is never called for the bits I care about I came up with the following approach: a) Add a new flag BR_FDB_DYNAMIC_LEARNED, which is set to 1 iff BR_FDB_ADDED_BY_USER or BR_FDB_LOCAL are set in br_create. Every time BR_FDB_ADDED_BY_USER or BR_FDB_LOCAL is set, also clear BR_FDB_DYNAMIC_LEARNED, and decrement the count if it was 1 before. This solves the problem of testing two bits at once, and wou...
