| 2018-11-15 | scsi: esas2r: use dma_set_mask_and_coherent | Christoph Hellwig | |
| The driver currently uses pci_set_dma_mask despite otherwise using the generic DMA API. Also move the dma_get_required_mask check before actually setting the dma mask so that we don't end up with inconsistent settings in corner cases.

| 2018-06-12 | treewide: kzalloc() -> kcalloc() | Kees Cook | |
| The kzalloc() function has a 2-factor argument form, kcalloc(). This patch replaces cases of: kzalloc(a * b, gfp) with: kcalloc(a * b, gfp) as well as handling cases of: kzalloc(a * b * c, gfp) with: kzalloc(array3_size(a, b, c), gfp) as it's slightly less ugly than: kzalloc_array(array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: kzalloc(4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ type TYPE; expression THING, E; @@ ( kzalloc( - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | kzalloc( - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression COUNT;

| 2018-04-20 | scsi: esas2r: use ktime_get_real_seconds() | Arnd Bergmann | |
| do_gettimeofday() is deprecated because of the y2038 overflow. Here, we use the result to pass into a 32-bit field in the firmware, which still risks an overflow, but if the firmware is written to expect unsigned values, it can at least last until y2106, and there is not much we can do about it. This changes do_gettimeofday() to ktime_get_real_seconds(), which at least simplifies the code a bit, and avoids the deprecated interface. I'm adding a comment about the overflow to document what happens. Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com> | |||

| Previously the code embedded the kernel's test_bit/clear_bit functions in wrappers that accepted u32 parameters.
