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.
