- adj. Capable of being freed (as an allocated resource).
Java, OCaml, and other static languages have a generational GC, which means that only recent allocations are frequently checked (the older an object is, the less likely it is to be freeable).
A buffer can be flagged as not freeable by kfree_skb () (see below). kfree_skb () releases a buffer, and if skb - > sk is set, it lowers the memory use counts of the socket (sk).
The second column after Chunk shows the start address of a chunk, sz = means chunk size, the next column shows the type of a chunk (free, freeable, recreate, perm, R-free, R-freeable).
