  "message": "fs: optimize out 16 bytes worth of padding in struct inode\n\nRearrange the fields in struct inode so that on an x86_64 system,\nfields that require 8-byte alignment don\u0027t end up causing 4-byte holes\nin the structure.  It reduces the size of struct inode from 568 bytes\nto 552 bytes.\n\nAlso move the fields protected by i_lock (i_blocks, i_bytes, and\ni_size) into the same cache line as i_lock.\n\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\n",
