debugfs -R 'stat <inode_nr> ' /dev/sda1 returns a result where there is a field
crtime which i believe represents the creation date of a file pointed to by inode numbered inode_nr. I use this on an ext4 fs.
I know that the inode stores access_time, modification_time and change_time but not birth of a file
So my question is where is the creation time stored or how does the debugfs command retrieve it?
