My 6.16 configuration

I remember from the log that you sent, there were quite a lot of failures, over
9000 of them.

Are you sure your scripts handles this?

e4defrag -v uBlock0\@raymondhill.net.xpi; echo $?
e4defrag 1.47.2 (1-Jan-2025)
ext4 defragmentation for uBlock0@raymondhill.net.xpi
[1/1]uBlock0@raymondhill.net.xpi:         0%
        Failed to defrag with EXT4_IOC_MOVE_EXT ioctl:Success   [ NG ]
 Success:                       [0/1]
1

So, it's "successful" except it's not.

> is specific to Artem's kernel or hardware configuration.

I thought ext4 code is quite independent from the rest of the kernel and no
other kernel options can possibly affect it.

gzip -d < /proc/config.gz | grep -i ext4
CONFIG_EXT4_FS=y
CONFIG_EXT4_USE_FOR_EXT2=y
CONFIG_EXT4_FS_POSIX_ACL=y
CONFIG_EXT4_FS_SECURITY=y
# CONFIG_EXT4_DEBUG is not set
