Make zram syslog error reporting more consistent. We have random error levels in some places. For example, critical errors like "Error allocating memory for compressed page" and "Unable to allocate temp memory" are reported as KERN_INFO messages. a) Reassign error levels Error messages that directly affect zram functionality -- pr_err(): Error allocating zram address table Error creating memory pool Decompression failed! err=%d, page=%u Unable to allocate temp memory Compression failed! err=%d Error allocating memory for compressed page: %u, size=%zu Cannot initialise %s compressing backend Error allocating disk queue for device %d Error allocating disk structure for device %d Error creating sysfs group for device %d Unable to register zram-control class Unable to get major number Messages that do not affect functionality, but user must be warned (because sysfs attrs will be removed in this particular case) -- pr_warn(): %d (%s) Attribute %s (and others) will be removed. %s Messages that do not affect functionality and mostly are informative -- pr_info(): Cannot change max compression streams Can't change algorithm for initialized device Cannot change disksize for initialized device Added device: %s Removed device: %s b) Update sysfs_create_group() error message First, it lacks a trailing new line; add it. Second, every error message in zram_add() has a "for device %d" part, which makes errors more informative. Add missing part to "Error creating sysfs group" message.
