* xattr_handler: pass dentry and inode as separate arguments of ->get()Al Viro2016-04-101-2/+4

* xattr handlers: Simplify list operationAndreas Gruenbacher2015-12-131-27/+8
| | | | | | | | | | | | Change the list operation to only return whether or not an attribute should be listed. Copying the attribute names into the buffer is moved to the callers. Since the result only depends on the dentry and not on the attribute name, we do not pass the attribute name to list operations.

* vfs: Distinguish between full xattr names and proper prefixesAndreas Gruenbacher2015-12-061-3/+0
| | | | | | | | | | | | | | Add an additional "name" field to struct xattr_handler. When the name is set, the handler matches attributes with exactly that name. When the prefix is set instead, the handler matches attributes with the given prefix and with a non-empty suffix. This patch should avoid bugs like the one fixed in commit c361016a in the future.

* squashfs: xattr simplificationsAndreas Gruenbacher2015-11-131-59/+31
| | | | | | | | | | Now that the xattr handler is passed to the xattr handler operations, we have access to the attribute name prefix, so simplify the squashfs xattr handlers a bit.

* xattr handlers: Pass handler to operations instead of flagsAndreas Gruenbacher2015-11-131-14/+22
| | | | | | | | | | | | | The xattr_handler operations are currently all passed a file system specific flags value which the operations can use to disambiguate between different handlers; some file systems use that to distinguish the xattr namespace, for example. In some oprations, it would be useful to also have access to the handler prefix. To allow that, pass a pointer to the handler to operations instead of the flags value alone.

* squashfs: xattr fix sparse warningsStephen Hemminger2010-05-171-4/+4
| | | | | | | | | | Sparse does not like inline function declared without body, because it is not part of the standard kernel practice. The xattr_handler tables can be declared static.
