If create new file or open file during this gap, these files will not use inlinecrypt. Worse case, it may lead to data corruption if wrappedkey_v0 is enable. Thread A: Thread B: -f2fs_remount -f2fs_file_open or f2fs_new_inode -default_options <- clear SB_INLINECRYPT flag -fscrypt_select_encryption_impl -parse_options <- set SB_INLINECRYPT again |
