xattr handlers: Simplify list operation

2015-12-14T00:46:12+00:00

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.

xattr handlers: Pass handler to operations instead of flags

2015-11-14T01:34:32+00:00

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.

Pull MTD updates from Brian Norris:
 "Common MTD:

   - Add Kconfig option for keeping both the 'master' and 'partition'
     MTDs registered as devices.  This would really make a better
     default if we could do it over, as it allows a lot more flexibility
     in (1) determining the flash topology of the system from user-space
     and (2) adding temporary partitions at runtime (ioctl(BLKPG)).

     Unfortunately, this would possibly cause user-space breakage, as it
     will cause renumbering of the /dev/mtdX devices.  We'll see if we
     can change this in the future, as there have already been a few
     people looking for this feature, and I know others have just been
     working around our current limitations instead of fixing them this
     way.

   - Along with the previous change, add some additional information to
     sysfs, so user-space can read the offset of each partition within
     its master device

  SPI NOR:

   - add new device tree compatible binding to represent the
     mostly-compatible class of SPI NOR flash which can be detected by
     their extended JEDEC ID bytes, cutting down the duplication of our
     ID tables

   - misc.  new IDs

  Various other miscellaneous fixes and changes"

jffs2: allow to complete xattr integrity check on first GC scan

2012-05-14T04:32:36+00:00

Unlike file data integrity the xattr data integrity was not checked
before some explicit access to the attribute was made.

This could leave in the system a number of corrupted extended attributes
which will be detected only at access time and possibly at a very late
time compared to the time the corruption actually happened.

This patch adds the ability to check for extended attribute integrity
on first GC scan pass (similar to file data integrity check). This allows
for all present attributes to be completly verified before any use of them.

In order to work correctly this patch also needs the patch allowing
JFFS2 to discriminate between recoverable and non recoverable errors
on extended attributes.
