[PATCH v2 0/2] fuse: inode blocksize fixes for iomap integration

[Joanne Koong <joannelkoong@gmail.com>]

These 2 patches are fixes for inode blocksize usage in fuse.

The first is neededed to maintain current stat() behavior for clients in the
case where fuse uses cached values for stat, and the second is needed for
fuseblk filesystems as a workaround until fuse implements iomap for reads.
(A previous version of the 2nd patch was submitted earlier [1], which this
current verison supersedes). These two patches are submitted together since
the 2nd patch updates code changed in the 1st patch.

These patches are on top of Christian's vfs.fixes tree.

Thanks,
Joanne
