      sanitize xattr handler prototypes · 431547b3
      由 Christoph Hellwig 提交于 
      Add a flags argument to struct xattr_handler and pass it to all xattr
handler methods.  This allows using the same methods for multiple
handlers, e.g. for the ACL methods which perform exactly the same action
for the access and default ACLs, just using a different underlying
attribute.  With a little more groundwork it'll also allow sharing the
methods for the regular user/trusted/secure handlers in extN, ocfs2 and
jffs2 like it's already done for xfs in this patch.

Also change the inode argument to the handlers to a dentry to allow
using the handlers mechnism for filesystems that require it later,
e.g. cifs.

      [JFFS2] Fix potential memory leak of dead xattrs on unmount. · 2ad8ee71
      由 David Woodhouse 提交于 
      An xattr_datum which ends up orphaned should be freed by the GC 
thread. But if we umount before the GC thread is finished, or if we 
mount read-only and the GC thread never runs, they might never be 
freed. Clean them up during unmount, if there are any left.

      [JFFS2] Fix BUG() caused by failing to discard xattrs on deleted files. · 8ae5d312
      由 David Woodhouse 提交于 
      When we cannot mark nodes as obsolete, such as on NAND flash, we end up 
having to delete inodes with !nlink in jffs2_build_remove_unlinked_inode().
However, jffs2_build_xattr_subsystem() runs later than this, and will
attach an xref to the dead inode. Then later when the last nodes of that
dead inode are erased we hit a BUG() in jffs2_del_ino_cache() 
because we're not supposed to get there with an xattr still attached to 
the inode which is being killed.

The simple fix is to refrain from attaching xattrs to inodes with zero 
nlink, in jffs2_build_xattr_subsystem(). It's it's OK to trust nlink 
here because the file system isn't actually mounted yet, so there's no 
chance that a zero-nlink file could actually be alive still because 
it's open.

      [JFFS2] Tidy up licensing/copyright boilerplate. · c00c310e
      由 David Woodhouse 提交于 
      In particular, remove the bit in the LICENCE file about contacting
Red Hat for alternative arrangements. Their errant IS department broke
that arrangement a long time ago -- the policy of collecting copyright
assignments from contributors came to an end when the plug was pulled on
the servers hosting the project, without notice or reason.

We do still dual-license it for use with eCos, with the GPL+exception
licence approved by the FSF as being GPL-compatible. It's just that nobody
has the right to license it differently.

      [JFFS2] kill warning RE debug-only variables · a6b1d82d
      由 Jeff Garzik 提交于 
      gcc emits the following warning on a 'allmodconfig' build:

fs/jffs2/xattr.c: In function ‘unrefer_xattr_datum’:
fs/jffs2/xattr.c:402: warning: unused variable ‘version’
fs/jffs2/xattr.c:402: warning: unused variable ‘xid’

Given that these variables are only used in the debug printk, and they
merely remove a deref, we can easily kill the warning by adding the
derefs to the debug printk.

      [JFFS2][XATTR] Fix xd->refcnt race condition · c6e8c6cc
      由 KaiGai Kohei 提交于 
      When xd->refcnt is checked whether this xdatum should be released
or not, atomic_dec_and_lock() is used to ensure holding the
c->erase_completion_lock.

This fix change a specification of delete_xattr_datum().
Previously, it's only called when xd->refcnt equals zero.
(calling it with positive xd->refcnt cause a BUG())
If you applied this patch, the function checks whether
xd->refcnt is zero or not under the spinlock if necessary.
Then, it marks xd DEAD flahs and links with xattr_dead_list
or releases it immediately when xd->refcnt become zero.

      [JFFS2] Reduce visibility of raw_node_ref to upper layers of JFFS2 code. · 2f785402
      由 David Woodhouse 提交于 
      As the first step towards eliminating the ref->next_phys member and saving
memory by using an _array_ of struct jffs2_raw_node_ref per eraseblock,
stop the write functions from allocating their own refs; have them just
_reserve_ the appropriate number instead. Then jffs2_link_node_ref() can
just fill them in.

Use a linked list of pre-allocated refs in the superblock, for now. Once
we switch to an array, it'll just be a case of extending that array.
