Btw I still have my own patches didn't have the time to clean them, will try next week, last time they gave me ~7% speedup. I also have a question is someone of you guys planning to submit a talk to future Linux events about kdbus and sdbus ? I have a presentation not finished about kdbus, sd-bus coupled with GCC plugins to construct kdbus sandbox profiles during compilation thanks to sd-bus semantics, but never had the time to finish it :-D > The following changes since commit 384ede7c5f52ff89d90bf3008360c5f7c0d6fcbf: > > kdbus: pool: use __vfs_read() (2015-06-02 21:37:22 +0900) > > are available in the git repository at: > > https://github.com/systemd/linux.git tags/for-greg > > for you to fetch changes up to 9efa7187a1522f57d4022b943378703b09db6c1b: > > kdbus: no need to ref current->mm (2015-06-03 18:50:21 +0200) > > ---------------------------------------------------------------- > kdbus cleanups since 4.1 for Greg > > * Several cleanups to reduce locking in metadata collection and connection > management. > > * Translate CAPS between namespaces just like ./security/commoncaps.c does. > Previously we just dropped CAPS on namespace borders, now we translate them > according to the upstream translation rules. > > * IdAdd / IdRemove notifications are now forwarded to everyone.
