From 0e9876d8e88d81a35742e90048ab3784c49b910b Mon Sep 17 00:00:00 2001 From: Jeff Layton Date: Wed, 31 Jan 2024 18:01:42 -0500 Subject: [PATCH] filelock: fl_pid field should be signed int 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).
