Subject: [RFC v5 0/8] Additional kmsg devices

Dear All,

This is the fifth iteration of Marcin Niesluchowski's serie of patches
extending kmsg interface with ability to dynamically create (and destroy)
kmsg-like devices which can be used by userspace for logging.

This iteration introduces two changes:

1. selftests are rearranged to use kselftest.h API

2. A disputed  patch "add predefined _PID, _TID, _COMM keywords to kmsg*
   log dict" is removed - no chance it will be ever accepted. It is not
   critical for this patchset as a whole.

Best regards,
Paul

Marcin Niesluchowski (6):
  printk: add one function for storing log in proper format
  kmsg: introduce additional kmsg devices support
  kmsg: add additional buffers support to memory class
  kmsg: add function for adding and deleting additional buffers
  kmsg: add ioctl for adding and deleting kmsg* devices
  kmsg: add ioctl for kmsg* devices operating on buffers

Paul Osmialowski (2):
  printk: extract kmsg-related routines from printk.c to kmsg.c
  kmsg: selftests
