When we wrote some data by compress mode into a btrfs filesystem which was full of the fragments, the kernel will report: BTRFS warning (device xxx): Aborting unused transaction. The reason is: We can not find a long enough free space to store the compressed data because of the fragmentary free space, and the compressed data can not be splited, so the kernel outputed the above message. In fact, btrfs can deal with this problem very well: it fall back to uncompressed IO, split the uncompressed data into small ones, and then store them into to the fragmentary free space. So we shouldn't output the above warning message. Signed-off-by: Miao Xie <miaox@cn.fujitsu.com> --- fs/btrfs/inode.c | 2 +- 1 files changed, 1 insertions(+), 1 deletions(-)
