If your eol trouble is as same as example code below, my patch series
is not enough to fix it.

The patch posted by Simon Heimberg at 05 Oct is also required, because
working directory of child subrepo is updated as a part of cloning (=
inter repository cooperation).

========================================
Create source subrepo tree in LF EOL style:

  $ cat >> $HGRCPATH <<EOF
  > [extensions]
  > # enable globally
  > eol =
  > [eol]
  > native = LF
  > EOF

  $ cat > hgeol <<EOF
  > [patterns]
  > **.txt = native
  > EOF

  $ hg init parent
  $ hg init parent/child
  $ cp hgeol parent/child/.hgeol
  $ printf "first\nsecond\nthird\n" > parent/child/child.txt
  $ hg -R parent/child commit -Am '#0 at child'
  $ cp hgeol parent/.hgeol
  $ printf "first\nsecond\nthird\n" > parent/parent.txt
  $ echo 'child = child'  > parent/.hgsub
  $ hg -R parent commit -Am '#0 at parent'

Clone just only parent repo to prevent from updating working directory
with eol extension.

  $ hg clone -U parent cloned

Enable eol locally in "cloned" repo, and change native EOL style

  $ cat >> cloned/.hg/hgrc <<EOF
  > [extensions]
  > # enable locally in "cloned" repo
  > eol =
  > EOF
  $ cat >> $HGRCPATH <<EOF
  > [extensions]
  > # disable by default
  > eol = !
  > [eol]
  > # change native EOL style: e.g. work on Windows
  > native = CRLF
  > EOF

Update working directory of "cloned" repo: this also clone/update
"child" subrepo

  $ hg -R cloned update -C --config eol.abort=True --traceback

"cloned" and "cloned/child" should be cleaned: but current
implementation detects difference in "cloned/child", because working
directory of it was updated with eol extension enabled in "cloned" as
parent, even though it should not be enabled in "cloned/child" itself.

  $ hg -R cloned status -S
  $ hg -R cloned/child status
  $ hg -R cloned/child diff
