Qu, fstests ran fine on an aarch64 kvm with this patch set.
Do you mean subpage patchset? With 4K sector size? No way it can run fine... Long enough fsstress can crash the kernel with btrfs_csum_one_bio() unable to locate the corresponding ordered extent.
Further, I was running few hand tests as below, and it fails with - Unable to handle kernel paging. Test case looks something like.. On x86_64 create btrfs on a file 11g copy /usr into /test-mnt stops at enospc set compression property on the root sunvol run defrag with -czstd
I don't even consider compression a supported feature for subpage. Are you really talking about the subpage patchset with 4K sector size, on 64K page size AArch64? If really so, I appreciate your effort on testing very much, it means the patchset is doing way better than it is. But I don't really believe it's even true to pass fstests.... Thanks, Qu
