Dear all, I have one question about ext4_fallocate: For its parameters, offset & len, it will preallocate one space with length >= len, right? >From the code: map.m_lblk = offset >> blkbits; /* * We can't just convert len to max_blocks because * If blocksize = 4096 offset = 3072 and len = 2048 */ max_blocks = (EXT4_BLOCK_ALIGN(len + offset, blkbits) >> blkbits) - map.m_lblk; We can see that the target space is enlarged to the (floor, ceiling) of (offset, offset+len). Right? If I'm wrong, please correct me.
