No, from the log it's 3.2.7, so it does not conain the patch "increase the global block reserve estimates" the log shows lots of messages Mar 8 13:36:37 kernel: use_block_rsv: 7 callbacks suppressed Mar 8 13:36:37 kernel: ------------[ cut here ]------------ Mar 8 13:36:37 kernel: WARNING: at fs/btrfs/extent-tree.c:5985 btrfs_alloc_free_block+0xc5/0x292 [btrfs]() ...
