I've settled for a Debian without graphics and it works quite well AND it has
NiLFS2 support!
Testing it on one of my older test NiLFS2 images I had around it paniced when
I did this:
qemu-system-x86_64 -drive file=root.debian.fs,format=raw -accel
tcg,thread=multi -smp cpus=4 -m 4096 -drive
file=/usr/tmp/nilfs.4g.img,format=raw
....
mount.nilfs2 /dev/sdb1 /mnt
touch /mnt/UDF
wait a second or two
CRASH
Note that /mnt/UDF exists and is a directory. It gives a NULL pointer
dereference at 0xa8
Call trace:
__test_set_page_writeback+0x38c/0x3f0
nilfs_segctor_do_construct+0x190f
nilfs_segctor_construct+0x1f5
nilfs_segctor_thread+0x127
....
RIP: 0010:percpu_counter_add_batch+0x04
....
Do you like to receive a copy of this image? It used to work fine and should
only be touched by your NiLFS code.
With regards,
Reinoud
