With these changes in place, the patchset changes Ext4 to use mpage_readpage[s] instead of its own custom ext4_readpages() function. This is done to reduce duplicity of code across filesystems. Based on the reviews provided for this patchset, I will change F2FS to use mpage_readpage[s] and post the next version of this patchset to linux-fsdevel mailing list. The patchset also includes patches from previous postings i.e. patches to replace per-filesystem encryption config options with a single config option that affects all filesystems making use of fscrypt code.
