[PATCH] ext3: Enable atomic inode security labeling
This patch modifies ext3 to call the inode_init_security LSM hook to obtain the security attribute for a newly created inode and to set the resulting attribute on the new inode as part of the same transaction. This parallels the existing processing for setting ACLs on newly created inodes.
