| |
After throwing rb_trees at the problem sysfs_dirent increased in size by 6 pointers, or 48 bytes. Since the point of having struct sysfs_dirent is to keep the size down increasing in size that much seems unfortunate.
The following patches attack this problem and if I have counted right reduce the size of sysfs_dirent by 4 pointers on 64bit. Not quite where we were but reducing sysfs_dirent by 32bytes to 104 bytes is an improvement.
