Hi, Since update to 2.6.37 I can''t build openwrt on my btrfs buildroot anymore. I''m not sure if this is related to the other flush-btrfs-1 thread. plenty of diskspace is free: /dev/mapper/cruor-build 97G 68G 27G 73% /opt/build It always hangs when openwrt builds the ext4 image and runs tune2fs on it.

From: "Xiaowei.Hu" <xiaowei.hu at oracle.com> ocfs2_block_group_alloc_discontig() disables chain relink by setting ac->ac_allow_chain_relink = 0 because it grabs clusters from multiple cluster groups. It doesn't keep the credits for all chain relink,but ocfs2_claim_suballoc_bits overrides this in this call trace:

I''ve been working on running down intermittent ENOSPC issues. I can only seem to replicate ENOSPC errors when running zlib compression. However, I have been seeing similar ENOSPC errors to a lesser extent when playing with the LZ4HC patches. I apologize for not following up on this sooner, but I had drifted away from using zlib, and didn''t notice there was still an issue. My
