locks: Fix procfs output for file leases
Since commit 778fc546f749c588aa2f ("locks: fix tracking of inprogress
lease breaks"), leases break don't change @fl_type but modifies
@fl_flags. However, procfs's part haven't been updated.
Previously, for a breaking lease the target type was printed (see
target_leasetype()), as returns fcntl(F_GETLEASE). But now it's always
"READ", as F_UNLCK no longer means "breaking". Unlike the previous
one, this behaviour don't provide a complete description of the lease.
There are /proc/pid/fdinfo/ outputs for a lease (the same for READ and
WRITE) breaked by O_WRONLY.
-- before:
lock: 1: LEASE BREAKING READ 2558 08:03:815793 0 EOF
-- after:
lock: 1: LEASE BREAKING UNLCK 2558 08:03:815793 0 EOF
