Subject: [PATCH 00/11] vdso: Various cleanups
Date: Tue, 26 Aug 2025 08:17:03 +0200 [thread overview]
Message-ID: <20250826-vdso-cleanups-v1-0-d9b65750e49f@linutronix.de> (raw)
Various cleanups to the generic vDSO infrastructure and a patch for ARM
which was never applied.
This series has one trivial syntactic conflict with "dso/datastore: Allow
prefaulting by mlockall()" [0] and a semantic one with "sparc64: vdso:
Switch to generic vDSO library" [1], which still uses the removed
GENERIC_VDSO_DATA_STORE.
