Hello!
trying to use zram block device, shows the following:
# zramctl -f -s 16g # cat /sys/block/zram0/comp_algorithm lzo [lzo-rle] lz4 lz4hc 842 zstd # zramctl NAME ALGORITHM DISKSIZE DATA COMPR TOTAL STREAMS MOUNTPOINT /dev/zram0 lzo-rle 16G 10.4M 4K 112K 32
# mkfs.xfs /dev/zram0 ...
[ 71.095998] zram: Added device: zram0 [ 71.765591] zram0: detected capacity change from 0 to 17179869184 [ 80.058772] Kernel unaligned access at TPC[8f2534] lzo1x_1_do_compress+0x1b4/0x820 [ 80.073832] Kernel unaligned access at TPC[8f2534] lzo1x_1_do_compress+0x1b4/0x820 [ 80.073866] Kernel unaligned access at TPC[8f2534] lzo1x_1_do_compress+0x1b4/0x820 [ 80.074709] Kernel unaligned access at TPC[8f2534] lzo1x_1_do_compress+0x1b4/0x820 [ 80.074923] Kernel unaligned access at TPC[8f2534] lzo1x_1_do_compress+0x1b4/0x820
all other tested compression algorithms (lzo, lz4, lz4hc, deflate, 842) work without producing kernel TPC.
