ext4: remove unmeetable inconsisteny check from ext4_find_extent()
ext4_find_extent(), stripped down to the parts relevant to this patch, reads as ppos = 0; i = depth; while (i) { --i; ++ppos; if (unlikely(ppos > depth)) { ... ret = -EFSCORRUPTED; goto err; } } Due to the loop's bounds, the condition ppos > depth can never be met. Remove this dead code. Signed-off-by: Nicolai Stange <nicstange@gmail.com> Signed-off-by: Theodore Ts'o <tytso@mit.edu>
