From: Haavard Skinnemoen Date: Tue, 31 Oct 2006 19:01:11 +0000 (+0100) Subject: AVR32: Fix thinko in generic_find_next_zero_le_bit() X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=168c8fa32ff40d6caf7226a5abf2a0096f3393bf;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git AVR32: Fix thinko in generic_find_next_zero_le_bit() The existing implementation of this function seems to be looking for a one although it should be looking for a zero. This causes trouble for the ext2 filesystem, which tends to report -ENOSPC without this patch. Fix this by complementing each word before scanning.
