| Subject: xfs: fix integer truncation in xfs_bmap_remap_alloc |
| |
| From: Christoph Hellwig <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. |
