From ba139824fa06a97f2a3b1cc4c6085d10a83ec2b9 Mon Sep 17 00:00:00 2001 From: Jeremie Koenig Date: Tue, 17 Aug 2010 17:27:54 +0000 Subject: More cleanup possibilities * procfs.c, procfs.h: Extend the signature of the cleanup_contents callback in the procfs_node_ops structure to include the hook and contents_len. (cleanup_contents_with_free, cleanup_contents_with_vm_deallocate): New functions, can be used as a cleanup_contents callback for simple cases. * procfs_dir.c, procfs_dir.h (procfs_dir_make_node): Update, add a cleanup callback, make sure the cleanup callback is invoked if there is an error. * proclist.c (proclist_make_node), main.c (main): Update to match the new interfaces. --- procfs_dir.h | 9 +++++++-- 1 file changed, 7 insertions(+), 2 deletions(-) (limited to 'procfs_dir.h') diff --git a/procfs_dir.h b/procfs_dir.h index 1ba45ad0..4eb934e0 100644 --- a/procfs_dir.h +++ b/procfs_dir.h @@ -9,7 +9,12 @@ struct procfs_dir_entry }; /* A simple directory is built from a table of entries.
