Revert "sysfs: fix race between readdir and lseek"
This reverts commit 991f76f837bf22c5bb07261cfd86525a0a96650c in Linus'
tree which is f366c8f271888f48e15cc7c0ab70f184c220c8a4 in
linux-stable.git
It depends on ef3d0fd27e90f ("vfs: do (nearly) lockless generic_file_llseek")
which is available only in 3.2+.
When applied on 3.0 codebase, it causes A-A deadlock, whenever anyone does
seek() on sysfs, as both generic_file_llseek() and sysfs_dir_llseek() obtain
i_mutex.
