From: Pavel Begunkov <[email protected]> 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 Signed-off-by: Pavel Begunkov <[email protected]> --- fs/locks.c | 8 ++++---- 1 file changed, 4 insertions(+), 4 deletions(-) diff --git a/fs/locks.c b/fs/locks.c index 686eae21daf6..24d1db632f6c 100644 --- a/fs/locks.c +++ b/fs/locks.c @@ -2784,10 +2784,10 @@ static void lock_get_status(struct seq_file *f, struct file_lock *fl, ?
