Hello

I've stored data on a USB external hard drive using ext4 over LUKS2 and I'm getting the following error:
	kernel: EXT4-fs error (device dm-11): ext4_map_blocks:607: inode #8159552: block 959787320: comm git-annex:w: lblock 0 mapped>

I then stumbled upon that kernel bug [1] which matches my case as git-annex is making heavy use of symlinks. However I've faced this issue on the kernel 6.3.0 (linux-image-6.3.0-1-amd64 version 6.3.7-1) so it doesn't look to be actually addressed.

I've got 3 disks, 2 HDDs and 1 SSD, and oddly the failure only happens on the HDD, the SSD is running fine.
After reformatting my HDD without the inline_data feature, the issue has disappeared.

Are you able to reliably preoeduce the issue and can bisect it to the
introducing commit? 

Can you retest please with recent kernel, 6.3.11-1 and ideally 6.4.4-1
as recently uploaded to unstable?

Regards,
Salvatore
