JFFS2 driver under 2.4.31 fails to trigger garbage collection/compression

[Heinig Gerald]

Hello all,

First off, I hope this is the correct mailing list for jffs2 under kernel 2.4. If it isn't, my apologies and please point me to the correct site. Thanks in advance.

I have encountered a problem with the jffs2 flash filesystem in kernel version 2.4.31.
Booting an NFS-root Kernel version 2.4.25 and mounting the flash filesystem with a particular image will indicate 140 kbytes of free space and can be written to without any problems.
Mounting this filesystem under a 2.4.31 NFS-root kernel and trying to write to it gives an error of no space left on device with 0 kbytes free, which is incorrect.
The garbage collection / compression algorithm apparently fails to detect the dirty blocks and therefore does not remove them, leading to erroneous memory usage accounting.
I tried waiting for up to 2 hours for the compression algorithm to start, without success.

Anyone have any ideas.

Beste Grüße / Best regards
