[Devel] [PATCH] fused: save logrotate option to fstab

2017-08-17 Thread Dmitry Monakhov

currently one may run 'vstorage-mount -s' with -L option, but
it will affect only current mount w/o reflection to fstab opts.
In fact mount.fuse.vstorage already has parser for logrotate option, so
this patch makes this feature fully supported.

[Devel] [PATCH v2 21/27] proc connector: pass VE to event fillers

2017-08-17 Thread Stanislav Kinsburskiy

Precursor patch. VE will be used later to get proper pid and user namespaces
for correct event generation.

[Devel] [PATCH v2 24/27] proc connector: send events to both VEs if not in VE#0

2017-08-17 Thread Stanislav Kinsburskiy

This is needed to preserve current behaviour, when process in initial pid and
user namespaces (i.e. in VE#0) can receive events from all the processes in
the system.

[Devel] [PATCH v2 03/27] connector: introduce VE-aware get_cdev() helper

2017-08-17 Thread Stanislav Kinsburskiy

Once containerized, device won't be one and for all.
Thus make a helper template and use it instead of direct device object access.
Use ve0 for now.

A lot of code is duplicated in proc connector events handling.
This patch introduces generic even handler, which will be used by different
events.
