## crc32c_intel

* Archwiki (Ext4#Enabling_metadata_checksums)[https://wiki.archlinux.org/title/Ext4#Enabling_metadata_checksums]
  > If the CPU supports SSE 4.2, make sure the crc32c_intel 
  > kernel module is loaded in order to enable the hardware 
  > accelerated CRC32C algorithm

On a SSE4.2 capable system, `crc32c-intel` should be used, not `crc32c-generic`.

Check your CPU (see the `.install` script):
```shell
lscpu | grep sse4_2
```

Can be enabled with:
```shell
MODULES=('crc32c-intel')
```
