Subject: [PATCH 11/13] vfs: export __inode_permission() to modules
Date: Wed, 15 Aug 2012 17:48:18 +0200 [thread overview]
Message-ID: <1345045700-9062-12-git-send-email-miklos@szeredi.hu> (raw)
In-Reply-To: <1345045700-9062-1-git-send-email-miklos@szeredi.hu>
From: Miklos Szeredi <mszeredi@suse.cz>
We need to be able to check inode permissions (but not filesystem implied
permissions) for stackable filesystems. Expose this interface for overlayfs.
