From: Jeff Layton Date: Wed, 31 Jan 2024 23:01:42 +0000 (-0500) Subject: filelock: fl_pid field should be signed int X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0e9876d8e88d81a35742e90048ab3784c49b910b;p=linux.git 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).
