Hello,
I noticed aufs.ko with debug is only 150 KB. This is cool! I will leave
debug turned on from now, I thought it will be several megabytes so I
disabled debug, but 150 KB is OK :)
So I enabled debug and here is the result (attached)
Thank you

Hello,
Tomas M:
mount -o remount,add:1:/mnt/live/memory/images/some_dir
Then I start kbuildsycoca to refresh KDE menu.
Sometimes it is OK but after adding few branches this way dmesg shows
the error attached, after kbuildsycoca.
my configuration:
CONFIG_AUFS=m
CONFIG_AUFS_FAKE_DM=y
CONFIG_AUFS_BRANCH_MAX_1023=y
CONFIG_AUFS_SYSAUFS=y
CONFIG_AUFS_KSIZE_PATCH=y
there is approximately 10 branches in union.
I could not reproduce this problem, and I can't guess the cause.
Won't you enable CONFIG_AUFS_DEBUG and reproduce it? I hope BUG_ON
macro in somewhere can detect the problem. But I am not confident.
