Not sure why, but the following patches:

"fs: Report actual data processed by mem_copy()"
"fs: Share code between mem_write()/mem_read()"

appear to be missing and, as a result:

"fs: Avoid division in mem_copy()"

doesn't actually have mem_copy() function in it. Did the two patches
above just slipped through the cracks or was there a particular reason
you dropped them?

Thanks,
