# POSIX requires that record locks are preserved across an execve(2). But
|
|
# there's bug that record locks are released if process is multithreaded at the
|
|
# time that execve is called.
|
|
#
|
|
# Fixed by patch from Jeff Layton:
|
|
# locks: change POSIX lock ownership on execve when files_struct is displaced
|
|
