Please pardon my ignorance, here is a short description of above patches

9f0bbd8 logfs: query block device for number of pages to send with bio
This BUG was found when LogFS was used on KVM. The patch fixes
the problem by asking for underlaying block device the number
of pages to send with each BIO.

41b93bc logfs: maintain the ordering of meta-inode destruction
LogFS maintains file system meta-data in special inodes. These
inodes are releated to each other, therefore they must be
destroyed in a proper order.

ddb24bb logfs: create a pagecache page if it is not present

cd8bfa9 logfs: initialize the number of iovecs in bio
LogFS used to panic when it was created on an encrypted LVM
volume. The patch fixes the problem by properly initializing
the BIO.

d2dcd90 logfs: destroy the reserved inodes while unmounting

Sorry for multiple mails and inconvenience it might have caused.

Thanks and Regards,
Prasad
