Hello, all. This patchset reduces the size of sysfs_dirent to 88 byte from 136 on 64bit and to 52 from 76 on 32bit. Combined with forthcoming reclaimable sysfs directories, this will make sysfs much more scalable on very large machines and very small machines.
This patchset contains the following three patches. #01: move-s_active-functions-to-fs-sysfs-dir-c, prep for #02 #02: slim-down-sysfs_dirent-s_active #03: use-signly-linked-list-for-sysfs_dirent-tree I'm pretty sure #02 is a good idea but #03 is debatable. The code doesn't look much uglier after the conversion tho. Inputs welcome.
