  "message": "[GFS2] Reduce inode size by moving i_alloc out of line\n\nIt is possible to reduce the size of GFS2 inodes by taking the i_alloc\nstructure out of the gfs2_inode. This patch allocates the i_alloc\nstructure whenever its needed, and frees it afterward. This decreases\nthe amount of low memory we use at the expense of requiring a memory\nallocation for each page or partial page that we write. A quick test\nwith postmark shows that the overhead is not measurable and I also note\nthat OCFS2 use the same approach.\n\nIn the future I\u0027d like to solve the problem by shrinking down the size\nof the members of the i_alloc structure, but for now, this reduces the\nimmediate problem of using too much low-memory on x86 and doesn\u0027t add\ntoo much overhead.\n\nSigned-off-by: Steven Whitehouse \u003cswhiteho@redhat.com\u003e\n",
