How to calculate available memory when zram is used? Available+Swap free memeory is obviously bigger than I actually can use, because zram can compress memory by compression algorithm and zram compressed data will occupy memeory too. Is there any way to calculate available memory accurately?
I think of a way is to count the compression rate of zram in the kernel. The available memory is calculated as follows: available + swapfree - swapfree * compress ratio Is it reasonable?
