Vitaliy Filippov 9e507fd333 Fix typo in crc32_pad
Didn't affect anything though because it was only skipping < 4096 byte remainders

Vitaliy Filippov ddd755a0e6 Fix incorrect checksums for small initial writes in the old store
Details:
- Write size should be exactly csum_block_size (4k by default)
- Write should be made into a new object (unallocated space)
- In this case, the checksum of the block was calculated as if the block was
  padded with extra (2^32 - size) zero bytes due to a simple integer overflow
- As a cherry on the cake, such calculation was 'slightly' slow because it
  was processing almost 4 GB of zeroes for a small write

Vitaliy Filippov feaf7a15cf Use CRC32C implementation from ISA-L when available - enables VPCLMULQDQ version with AVX512 which is ~2x faster 2025-08-10 18:03:47 +03:00
