f2fs: fix to overcome inline_data floods (6e17bfbc) · Commits · 戴 / test

The scenario is: 1. create lots of node blocks 2. sync 3. write lots of inline_data -> got panic due to no free space In that case, we should flush node blocks when writing inline_data in #3, and trigger gc as well. Signed-off-by:
