In using the 4.5.2 Linux kernel to debug some ‘other problem’ I was unable to
use my squashfs file system with the kernel.
wending my way to ‘xz_wrapper.c’ I find the following structure definition in
the OpenWRT ’trunk’ version of kernel sources:
struct comp_opts {
__le32 flags;
__le16 bit_opts;
__le16 fb;
__le32 dictionary_size;
};
However, for the standard Linux kernel 4.5.2 the same named file has the
following structure definitions:
struct disk_comp_opts {
__le32 dictionary_size;
__le32 flags;
};
struct comp_opts {
int dict_size;
};
The question is, how is it that there is this significant difference?
It seems that the structure should have been
struct disk_comp_opts {
__le32 dictionary_size;
__le32 flags;
/* Plus additional OpenWRT elements. */
};
