Hi,
I spent some time tonight trying to track down how to fix the issue of duplicate sysfs files and/or directories. This happens when you try to create a kobject with the same name in the same directory. The creation of the second kobject will fail, but the directory will remain in sysfs.
Now I know this isn't a normal operation, but it would be good to fix this eventually. I traced the issue down to fs/sysfs/dir.c:create_dir() and the check for: if (error && (error != -EEXIST)) {
Problem is, error is set to -EEXIST, so we don't clean up properly. Now I know we can't just not check for this, as if you do that error cleanup, the original kobject's sysfs entry gets very messed up (ls -l does not like it at all...)
But I can't seem to figure out what exactly we need to do to clean up properly here.
Do you, or anyone else, have any pointers or ideas?
thanks,
