fs: optimize out 16 bytes worth of padding in struct inode Rearrange the fields in struct inode so that on an x86_64 system, fields that require 8-byte alignment don't end up causing 4-byte holes in the structure. It reduces the size of struct inode from 568 bytes to 552 bytes. Also move the fields protected by i_lock (i_blocks, i_bytes, and i_size) into the same cache line as i_lock.
