Hi,

may I post a thought?

It seems strange to me that alloc_inode may set=20

#ifdef CONFIG_FS_POSIX_ACL
	inode->i_acl =3D inode->i_default_acl =3D ACL_NOT_CACHED;
#endif

[where ACL_NOT_CACHED is #define ACL_NOT_CACHED ((void *)(-1))]

meanwhile say jffs2_init_acl_post use ACL_NOT_CACHED
as a valid value and trying to parse it.

But perhaps, I miss something.
