- # The zram sysfs node 'disksize' value can be either in bytes,
- # or you can use mem suffixes. But in some old kernels, mem
- # suffixes are not supported, for example, in RHEL6.6GA's kernel
- # layer, it uses strict_strtoull() to parse disksize which does
- # not support mem suffixes, in some newer kernels, they use
- # memparse() which supports mem suffixes. So here we just use
- # bytes to make sure everything works correctly.
