This should be checked to ensure the ubifs_assert is working as
intended, I've done the suggested annotation in this patch.

This looks like a bugfix as your tmp was a u32 so there was truncation in
the atime, mtime, ctime value, probably not intentional, add a tmp_le64
and use it here.

Read from the annotated union member instead.

Do byteshifting at compile time of the flag value.  Annotate the saved_flags
as le32.

Should be checked if the truncation was intentional, I've changed the
printk to print the full width.

Some flash media are capable of reading sequentially at faster rates.
UBIFS bulk-read facility is designed to take advantage of that, by
reading in one go consecutive data nodes that are also located
consecutively in the same LEB.

Read speed on Arm platform with OneNAND goes from 17 MiB/s to
19 MiB/s.
