  "message": "[PATCH] fs: reorder some \u0027struct inode\u0027 fields to speedup i_size manipulations\n\nOn 32bits SMP platforms, 64bits i_size is protected by a seqcount\n(i_size_seqcount).\n\nWhen i_size is read or written, i_size_seqcount is read/written as well, so\nit make sense to group these two fields together in the same cache line.\n\nThis patch moves i_size_seqcount next to i_size, and also moves i_version\nto let offsetof(struct inode, i_size) being 0x40 instead of 0x3c (for\n32bits platforms).\n\nFor 64 bits platforms, i_size_seqcount doesnt exist, and the move of a\n\u0027long i_version\u0027 should not introduce a new hole because of padding.\n\nSigned-off-by: Eric Dumazet \u003cdada1@cosmosbay.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n",
