Subject: f2fs: add f2fs_balance_fs for direct IO
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=79e35dc3c23dd2ac9f8681361026c82b71a0b006;p=linux-beck.git

f2fs: add f2fs_balance_fs for direct IO

Otherwise, if a large amount of direct IO writes were done, the
segment allocation may be failed because no enough segments are gced.

Changes:

v2: add f2fs_balance_fs into __get_data_block instead of f2fs_direct_IO.
