Julia Lawall	60d877334f	fs/ceph: introduce missing kfree ... Error handling code following a kmalloc should free the allocated data. The semantic match that finds this problem is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r exists@ local idexpression x; statement S; expression E; identifier f,f1,l; position p1,p2; expression *ptr != NULL; @@ x@p1 = \(kmalloc\|kzalloc\|kcalloc\)(...); ... if (x == NULL) S <... when != x when != if (...) { <+...x...+> } ( x->f1 = E | (x->f1 == NULL || ...) | f(...,x->f1,...) ) ...> ( return \(0\|<+...x...+>\|ptr\); | return@p2 ...; ) @script:python@ p1 << r.p1; p2 << r.p2; @@ print "* file: %s kmalloc %s return %s" % (p1[0].file,p1[0].line,p2[0].line) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Sage Weil <sage@newdream.net>	2009-11-21 13:05:14 -08:00

Sage Weil	355da1eb7a	ceph: inode operations ... Inode cache and inode operations. We also include routines to incorporate metadata structures returned by the MDS into the client cache, and some helpers to deal with file capabilities and metadata leases. The bulk of that work is done by fill_inode() and fill_trace(). Signed-off-by: Sage Weil <sage@newdream.net>	2009-10-06 11:31:08 -07:00
