Documentation/filesystems/sysfs.txt: Attributes can be exported for kobjects in the form of regular files in the filesystem. Sysfs forwards file I/O operations to methods defined for the attributes, providing a means to read and write kernel attributes. Attributes should be ASCII text files, preferably with only one value per file. It is noted that it may not be efficient to contain only one value per file, so it is socially acceptable to express an array of values of the same type. I don't remember that last sentence; it was apparently added since the last time I've looked at it. Originally, the requirement that each sysfs file (which was supposed to be an kobject attribute) was required to be a single value. Now there's an escape hatch for "efficiency", which is nice.... > So you're suggesting to have three sysfs files ? > > errors_count > first_error_time > last_error_time Yes, that's what I was suggesting. - Ted -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
