#     reiserfs: update reiserfs_xattrs_initialized() condition
#     
#     syzbot is reporting NULL pointer dereference at reiserfs_security_init()
#     [1], for commit ab17c4f02156c4f7 ("reiserfs: fixup xattr_root caching")
#     is assuming that REISERFS_SB(s)->xattr_root != NULL in
#     reiserfs_xattr_jcreate_nblocks() despite that commit made
#     REISERFS_SB(sb)->priv_root != NULL && REISERFS_SB(s)->xattr_root == NULL
#     case possible.
#     
#     I guess that commit 6cb4aff0a77cc0e6 ("reiserfs: fix oops while creating
#     privroot with selinux enabled") wanted to check xattr_root != NULL
#     before reiserfs_xattr_jcreate_nblocks(), for the changelog is talking
#     about the xattr root.
#     
#       The issue is that while creating the privroot during mount
#       reiserfs_security_init calls reiserfs_xattr_jcreate_nblocks which
#       dereferences the xattr root. The xattr root doesn't exist, so we get
#       an oops.
#     
#     Therefore, update reiserfs_xattrs_initialized() to check both the
#     privroot and the xattr root.
