Subject: [RFC v2 0/9] Additional kmsg devices
Date: Mon, 12 Oct 2015 11:29:08 +0200	[thread overview]
Message-ID: <1444642157-32618-1-git-send-email-p.osmialowsk@samsung.com> (raw)

Dear All,

This is the second 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.

Some changes were introduced in this iteration:

- all occurences of '#ifdef CONFIG_PRINTK' removed from drivers/char/mem.c

- printk related code moved to kernel/printk/printk.c

- use of VMCOREINFO_STRUCT_SIZE as suggested by Petr Mladek

- selftests for kmsg added (shape of testing infrastructure based on
  kdbus selftests)

Best regards,
Paul

Marcin Niesluchowski (8):
  printk: move code regarding log message storing format
  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 predefined _PID, _TID, _COMM keywords to kmsg* log dict
  kmsg: add ioctl for adding and deleting kmsg* devices
  kmsg: add ioctl for kmsg* devices operating on buffers

Paul Osmialowski (1):
  kmsg: selftests
