Writing Inodes Back To Disk

Writing inodes back to disk is done using the super-block's write_inode operation, and the stamfs_write_inode() function, which simply invokes stamfs_inode_write_ino():

• Load the inode's block from disk.
• Update it with data from the VFS inode struct.
• Mark the inode's buffer_head as dirty - it'll be written by bdflush or during unmount.
• Unless we were asked to do this synchronously - in which case we force an immediate buffer_head write.
