Subject: [PATCH next 0/2] kallsyms: optimise symbol search by name
Date: Wed, 30 Sep 2026 14:21:06 +0100 [thread overview]
Message-ID: <20260930132109.260597-1-david.laight.linux@gmail.com> (raw)
Patch 1 is from Jim Crome, included so the patch series builds.
This is currently in mm-nonmm-unstable
Patch 2 Removes the linear scan from the 'search by name' binary bisect.
Data size unchanged for 'sane' kernels.
Seems to work (I'm running it on this system), but I haven't got any performance
numbers.

kallsyms: Match compressed tokens on the fly during binary search
