This is a 10% reduction\nin the inode size on a UP kernel that is configured in a production mode\n(i.e., with no spinlock or other debugging functions enabled; if you want to\nsave memory taken up by in-core inodes, the first thing you should do is\ndisable the debugging options; they are responsible for a huge amount of bloat\nin the VFS inode structure).\n\nThis patch:\n\nThe filesystem or device-specific pointer in the inode is inside a union,\nwhich is pretty pointless given that all 30+ users of this field have been\nusing the void pointer. Get rid of the union and rename it to i_private, with\na comment to explain who is allowed to use the void pointer. This is just a\ncleanup, but it allows us to reuse the union \u0027u\u0027 for something something where\nthe union will actually be used.\n\n[judith@osdl.org: powerpc build fix]\nSigned-off-by: \"Theodore Ts\u0027o\" \u003ctytso@mit.edu\u003e\nSigned-off-by: Judith Lebzelter \u003cjudith@osdl.org\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "873302c71c0e60234eb187b15f83c2d79e84c40a", "tree": "65288ff5a46b03c69ffc0b0634ab5bed37f1bc9a", "parents": [ "0a0898cf413876d4ed6e371f3e04bf38600a9205" ], "author": { "name": "Miklos Szeredi", "email": "miklos@szeredi.hu", "time": "Sun Jul 30 03:04:10 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Mon Jul 31 13:28:43 2006 -0700" }, "message": "[PATCH] fuse: fix typo\n\nSigned-off-by: Miklos Szeredi \u003cmiklos@szeredi.hu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "bafa96541b250a7051e3fbc5de6e8369daf8ffec", "tree": "9b758c424fcda2d263c71f25358bb65a0abc15d4", "parents": [ "51eb01e73599efb88c6c20b1c226d20309a75450" ], "author": { "name": "Miklos Szeredi", "email": "miklos@szeredi.hu", "time": "Sun Jun 25 05:48:51 2006 -0700" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@g5.osdl.org", "time": "Sun Jun 25 10:01:19 2006 -0700" }, "message": "[PATCH] fuse: add control filesystem\n\nAdd a control filesystem to fuse, replacing the attributes currently exported\nthrough sysfs.
