I forgot to update the expected output. Ignore this.

There is a long lived bug that btrfs wait for readahead to finish indefinitely when readahead zone is inserted into seed devices. Current write size to the file "foobar" is too small to run readahead before the replacing on seed device. So, increase the write size to reproduce the issue. Following patch fixes it: "btrfs: start readahead also in seed devices" Signed-off-by: Naohiro Aota <naohiro.aota@wdc.com> --- tests/btrfs/163 | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
