Subject: [RESEND PATCH v3 0/4] fscache,erofs: fscache-based demand-read semantics (fscache part)

Hi David,

This patchset is from [1], which is all fscache part related, in prep
for the newly introduced on-demand read semantics.

The previous patch 5 [2] from [1] is still under modification according
to the comments from Greg. Thus it is not included in this patchset
yet, and will be sent out later.

Whilst these four patches in this patchset are basically trivial cleanup
codes. I do appreciate if you coud give some hint on this work.

Thanks.
