Christophe Vu-Brugier c9f727219f exfat: fix i_blocks for files truncated over 4 GiB ... [ Upstream commit 92fba084b7 ] In exfat_truncate(), the computation of inode->i_blocks is wrong if the file is larger than 4 GiB because a 32-bit variable is used as a mask. This is fixed and simplified by using round_up(). Also fix the same buggy computation in exfat_read_root() and another (correct) one in exfat_fill_inode(). The latter was fixed another way last month but can be simplified by using round_up() as well. See: commit 0c336d6e33 ("exfat: fix incorrect loading of i_blocks for large files") Fixes: 98d917047e ("exfat: add file operations") Cc: stable@vger.kernel.org # v5.7+ Suggested-by: Matthew Wilcox <willy@infradead.org> Reviewed-by: Sungjong Seo <sj1557.seo@samsung.com> Signed-off-by: Christophe Vu-Brugier <christophe.vu-brugier@seagate.com> Signed-off-by: Namjae Jeon <linkinjeon@kernel.org> Signed-off-by: Sasha Levin <sashal@kernel.org>		2022-03-08 19:12:32 +01:00
