This supports "off", "user-based", and + "fs-based". In "off" mode (default), f2fs does not pass + down hints. In "user-based" mode, f2fs tries to pass + down hints given by users.

Currently supports "posix" + and "strict". In "posix" mode, which is default, fsync + will follow POSIX semantics and does a light operation + to improve the filesystem performance. In "strict" mode, + fsync will be heavy and behaves in line with xfs, ext4 + and btrfs, where xfstest generic/342 will pass, but the + performance will regress. +test_dummy_encryption Enable dummy encryption, which provides a fake fscrypt + context. The fake fscrypt context is used by xfstests. ================================================================================ DEBUGFS ENTRIES |
