[PATCH v3 01/47] filelock: fl_pid field should be signed int

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]


This field has been unsigned for a very long time, but most users of the
struct file_lock and the file locking internals themselves treat it as a
signed value. Change it to be pid_t (which is a signed int).
