atime



Hi
What was the purpose of reserving the inode for atime file (nilfs2_fs.h)
#define NILFS_ATIME_INO        7    /* Atime file (reserved) */
Correct me if I'm wrong, but it seems to me that updating atime on the disk
result in creating more chekpoints. So spesial file in predetermined place can store atime of all files in the system and spare the need of checkpointings of many segments. Also can you please share your thoughts about the atime implementation on nilfs?
Thank you
David
