  "message": "[PATCH] Use __read_mostly on some hot fs variables\n\nI discovered on oprofile hunting on a SMP platform that dentry lookups were\nslowed down because d_hash_mask, d_hash_shift and dentry_hashtable were in\na cache line that contained inodes_stat.  So each time inodes_stats is\nchanged by a cpu, other cpus have to refill their cache line.\n\nThis patch moves some variables to the __read_mostly section, in order to\navoid false sharing.  RCU dentry lookups can go full speed.\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",
