Once upon a time a bunch of serial drivers used to provide that; today it's only amiserial and it's FUBAR - the structure being copied to userland includes kernel pointers, fields with config-dependent size, etc. No userland code using it could possibly survive - e.g. enabling lockdep definitely changes the layout. Besides, it's a massive infoleak. Kill it. If somebody needs that data for debugging purposes, they can bloody well expose it saner ways. Assuming anyone does debugging of amiserial in the first place, that is. Signed-off-by: Al Viro <viro@zeniv.linux.org.uk> |
