ceph: fix duplicate increment of opened_inodes metric
[ Upstream commit 973e524 ] opened_inodes is incremented twice when the same inode is opened twice with O_RDONLY and O_WRONLY respectively. To reproduce, run this python script, then check the metrics: import os for _ in range(10000): fd_r = os.open('a', os.O_RDONLY) fd_w = os.open('a', os.O_WRONLY) os.close(fd_r) os.close(fd_w) Fixes: 1dd8d47 ("ceph: metrics for opened files, pinned caps and opened inodes") Signed-off-by: Hu Weiwen <sehuww@mail.scut.edu.cn> Reviewed-by: Xiubo Li <xiubli@redhat.com> Signed-off-by: Ilya Dryomov <idryomov@gmail.com> Signed-off-by: Sasha Levin <sashal@kernel.org>
