Hello RT-list!
I'm pleased to announce the 4.4.229-rt200 stable release.
This release is just an update to the new stable 4.4.215 version.
Note: This update required dealing with a conflict in net/core/dev.c, where
devnet_rename_seq was moved from a seqence count to an RWSEM and renamed
to devnet_rename_sem. If you encounter runtime issues that show tracebacks
in net/core/dev.c, please let me know.
Patch "net: Add a mutex around devnet_rename_seq" dropped in favour of
602c47fbf46b ("net: core: device_rename: Use rwsem instead of a seqcount")
Known issues:
sigwaittest with hackbench as workload is able to trigger a crash on x86_64,
the same as reported for the v4.4.220-rt196 release. The crash seems to
be triggered by a BPF program. IIRC, BPF was never supported in v4.4-rt
and I just forgot to disable in my configuration.
You can get this release via the git tree at:
