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
