[PATCH v5 1/3] man/man2const/PR_FUTEX_HASH.2const: Update as of Linux v6.17-rc2
From: Sebastian Andrzej Siewior
Date: Tue Aug 19 2025 - 03:21:37 EST
The PR_FUTEX_HASH prctl interface was updated shortly before the release
of v6.16. The changes are:
- the functionality was disabled in v6.16 and enabled v6.17-rc1 after
some updates the address performance concerns.
- the "IMMUTABLE" functionality was removed.
Update the page accordingly.
