Subject: [PATCH 08/25] xfs: fix integer truncation in xfs_bmap_remap_alloc
Date: Sat, 3 Jun 2017 15:18:19 +0200 [thread overview]
Message-ID: <20170603131836.26661-9-hch@lst.de> (raw)
In-Reply-To: <20170603131836.26661-1-hch@lst.de>
commit 52813fb13ff90bd9c39a93446cbf1103c290b6e9 upstream.
bno should be a xfs_fsblock_t, which is 64-bit wides instead of a
xfs_aglock_t, which truncates the value to 32 bits.
