Subject: fs/ntfs3: Use kmalloc_array for allocating multiple elements
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=92f017c4aee6e2bb79593adeacccbea3afe62223;p=linux.git

fs/ntfs3: Use kmalloc_array for allocating multiple elements

Prefer using kmalloc_array(a, b) over kmalloc(a * b) as this
improves semantics since kmalloc is intended for allocating an
array of memory.
