Might be related to this:

: Convert code away from ->read_proc/->write_proc interfaces.  Switch to
: proc_create()/proc_create_data() which make addition of proc entries
: reliable wrt NULL ->proc_fops, NULL ->data and so on.
: Problem with ->read_proc et al is described here commit
: 786d7e1612f0b0adb6046f19b906609e4fe8b1ba "Fix rmmod/read/write races in
