libext2fs: zero blocks via FALLOC_FL_ZERO_RANGE in ext2fs_zero_blocks Plumb a new call into the IO manager to support translating ext2fs_zero_blocks calls into the equivalent FALLOC_FL_ZERO_RANGE fallocate flag primitive when possible. This patch provides _only_ support for file-based images. Signed-off-by: Darrick J. Wong <darrick.wong@oracle.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
