In mount_load_proc_self_mountinfo(), device_found_node() is synchronously called during the traversal of mountinfo entries. When there are a large number of mount points, and the device types are not significantly different, this results in excessive time consumption during device discovery, causing a performance bottleneck. This issue is particularly prominent on servers with a large number of cores in IDC. This patch decouples device discovery from the mountinfo traversal process, avoiding redundant device operations. As a result, it significantly improves performance, especially in environments with numerous mount points. Signed-off-by: Chen Guanqiao <chen.chenchacha@foxmail.com>
