So it\u0027s\nsad to see it going neglected.\n\nWith CONFIG_PROFILING turned on (which is probably the common case at least\nfor distros and kernel developers), sizeof(struct dcache) \u003d\u003d 208 here\n(64-bit). This gives 19 objects per slab.\n\nI packed d_mounted into a hole, and took another 4 bytes off the inline\nname length to take the padding out from the end of the structure. This\nshinks it to 200 bytes. I could have gone the other way and increased the\nlength to 40, but I\u0027m aiming for a magic number, read on...\n\nI then got rid of the d_cookie pointer. This shrinks it to 192 bytes. Rant:\nwhy was this ever a good idea? The cookie system should increase its hash\nsize or use a tree or something if lookups are a problem. Also the \"fast\ndcookie lookups\" in oprofile should be moved into the dcookie code -- how\ncan oprofile possibly care about the dcookie_mutex? It gets dropped after\nget_dcookie() returns so it can\u0027t be providing any sort of protection.\n\nAt 192 bytes, 21 objects fit into a 4K page, saving about 3MB on my system\nwith ~140 000 entries allocated. 192 is also a multiple of 64, so we get\nnice cacheline alignment on 64 and 32 byte line systems -- any given dentry\nwill now require 3 cachelines to touch all fields wheras previously it\nwould require 4.\n\nI know the inline name size was chosen quite carefully, however with the\nreduction in cacheline footprint, it should actually be just about as fast\nto do a name lookup for a 36 character name as it was before the patch (and\nfaster for other sizes). The memory footprint savings for names which are\n\u003c\u003d 32 or \u003e 36 bytes long should more than make up for the memory cost for\n33-36 byte names.\n\nPerformance is a feature...\n\nSigned-off-by: Al Viro \u003cviro@zeniv.linux.org.uk\u003e\n" }, { "commit": "cf28b4863f9ee8f122e8ff3ac0d403e07ba9c6d9", "tree": "65c91f6911b34c32e517938289621ce0e7baeaf3", "parents": [ "c32c2f63a9d6c953aaf168c0b2551da9734f76d2" ], "author": { "name": "Jan Blunck", "email": "jblunck@suse.de", "time": "Thu Feb 14 19:38:44 2008 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.linux-foundation.org", "time": "Thu Feb 14 21:17:09 2008 -0800" }, "message": "d_path: Make d_path() use a struct path\n\nd_path() is used on a \u003cdentry,vfsmount\u003e pair.
