X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=f85b287a01237857a50c93868231f7e831581a27;p=linux-beck.git

ext4: error handling fix in ext4_ext_convert_to_initialized()

When allocated is unsigned it breaks the error handling at the end
of the function when we call:
	allocated = ext4_split_extent(...);
	if (allocated < 0)
		err = allocated;

I've made it a signed int instead of unsigned.
