[PATCH 5.4 219/261] dm crypt: avoid truncating the logical block size
From: Greg Kroah-Hartman
Date: Fri Jun 19 2020 - 11:21:52 EST
From: Eric Biggers <ebiggers@xxxxxxxxxx>
commit 64611a15ca9da91ff532982429c44686f4593b5f upstream.
queue_limits::logical_block_size got changed from unsigned short to
unsigned int, but it was forgotten to update crypt_io_hints() to use the
new type. Fix it.
Fixes: ad6bf88a6c19 ("block: fix an integer overflow in logical block size")
