Bug ID: 23478
Summary: bpf: multi-key associative arrays
Product: systemtap
Version: unspecified
Status: UNCONFIRMED
Severity: normal
Priority: P2
Component: bpf
Assignee: systemtap at sourceware dot org
Reporter: me at serhei dot io
Target Milestone: ---
From the 'language features' brainstorm:
# More complex structures: multi-key associative arrays
It's theoretically possible to have a large struct as the key to a hash map.
Thus, a key could literally be a structure with 2 (or more) embedded strings.
It seemed to work fine when I used a 128-byte map key size, so two 64-byte
string keys should be doable at the very least.
