exfat: fix missing REQ_SYNC in exfat_update_bhs()

2022-01-10T02:00:04+00:00

If 'dirsync' is enabled, all directory updates within the
filesystem should be done synchronously. exfat_update_bh()
does as this, but exfat_update_bhs() does not.

exfat: fix i_blocks for files truncated over 4 GiB

2022-01-10T02:00:02+00:00

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 0c336d6e33f4 ("exfat: fix incorrect loading of i_blocks for
                        large files")

exfat: reuse exfat_inode_info variable instead of calling EXFAT_I()

2022-01-10T02:00:02+00:00

Also add a local "struct exfat_inode_info *ei" variable to
exfat_truncate() to simplify the code.

exfat: fix incorrect loading of i_blocks for large files

2021-10-31T22:49:21+00:00

When calculating i_blocks, there was a mistake that was masked with a
32-bit variable. So i_blocks for files larger than 4 GiB had incorrect
values. Mask with a 64-bit variable instead of 32-bit one.
