Jeff Mahoney fb2162df74 reiserfs: fix corruption during shrinking of xattrs ... Commit 48b32a3553 ("reiserfs: use generic xattr handlers") introduced a problem that causes corruption when extended attributes are replaced with a smaller value. The issue is that the reiserfs_setattr to shrink the xattr file was moved from before the write to after the write. The root issue has always been in the reiserfs xattr code, but was papered over by the fact that in the shrink case, the file would just be expanded again while the xattr was written. The end result is that the last 8 bytes of xattr data are lost. This patch fixes it to use new_size.
