[PATCH] decompress: change length arguments to long

Sascha Hauer s.hauer at pengutronix.de
Tue Feb 6 01:48:38 PST 2024


In order to support decompression of files > 2GiB Linux has changed
the prototypes of decompression functions from

int uncompress(unsigned char *inbuf, int len,
	       int(*fill)(void*, unsigned int),
	       int(*flush)(void*, unsigned int),
	       unsigned char *output,
	       int *pos,
	       void(*error_fn)(char *x));

to

int uncompress(unsigned char *inbuf, long len,
	       long(*fill)(void*, unsigned long),
	       long(*flush)(void*, unsigned long),
	       unsigned char *output,
	       long *pos,
	       void(*error_fn)(char *x));

Do likewise in barebox for easier code sharing with Linux.
