Send a FS_ERROR message via fsnotify to a userspace monitoring tool whenever a ext4 error condition is triggered. This follows the existing error conditions in ext4, so it is hooked to the ext4_error* functions. It also follows the current dmesg reporting in the format. The filesystem message is composed mostly by the string that would be otherwise printed in dmesg. A new ext4 specific record format is exposed in the uapi, such that a monitoring tool knows what to expect when listening errors of an ext4 filesystem.
