| |
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
