## Summary 1. Cache all file node info to ram when file system is mounted, then it can avoid emmc/mmcsd access to improve access speed when using romfs_open/romfs_opendir/romfs_readdir. 2. Save file path for every open file, then we can get file path by ioctl with FIOC_FILEPATH. ## Impact 1. Improve romfs access speed when enable CONFIG_FS_ROMFS_CACHE_NODE. 2. When enable CONFIG_FS_ROMFS_CACHE_NODE, the cache operation consumes at least 20bytes for each file. 3. look file path for every fd when cat /proc/pid/group/fd. ## Testing N/A -- This is an automated message from the Apache Git Service.
