Subject: [PATCH] Use lzo-rle for 16kb page kernel

Test: Checked zram compression with 4KB and 16KB kernel
======== Using 4KB kernel================
$ adb shell getconf PAGE_SIZE
4096
$ adb shell cat  /sys/block/zram0/comp_algorithm
[lz77eh] zstd deflate lz4 lzo-rle lzo
======== Using 16KB kernel================
$ adb root
restarting adbd as root
$ adb shell cat  /sys/block/zram0/comp_algorithm
lz77eh zstd deflate lz4 [lzo-rle] lzo
$ adb shell getconf PAGE_SIZE
16384
