Subject: [PATCH v3 0/2] printk: console: Per-console loglevels
Message-ID: <cover.1658339046.git.chris@chrisdown.name>
MIME-Version: 1.0
Content-Type: text/plain; charset=us-ascii
Content-Disposition: inline
User-Agent: Mutt/2.2.6 (2022-06-05)
Precedence: bulk

v3:

- Update to work with John's kthread patches
- Remove force_console_loglevel, now we only have global and local levels
- Remove minimum_console_loglevel control and document how to change it
- The minimum loglevel is now only honoured on setting global/local level
- Add ignore_per_console_loglevel
- Return -EINVAL if trying to set below minimum console level
- Add parser for named console= options
- Fix docs around ignore_loglevel: it can be changed at runtime
- Fix ordering in "in order of authority" docs
- Remove duplicated default_console_loglevel doc
- Only warn once on syslog() use

v2:

- Dynamically allocate struct device*
- Document sysfs attributes in Documentation/ABI/
- Use sysfs_emit() instead of sprintf() in dev sysfs files
- Remove WARN_ON() for device_add/IS_ERR(console_class)
- Remove "soon" comment for kernel.printk
- Fix !CONFIG_PRINTK build
- Fix device_unregister() NULL dereference if called before class setup
- Add new documentation to MAINTAINERS

Chris Down (2):
  printk: console: Create console= parser that supports named options
  printk: console: Support console-specific loglevels
