Signed-off-by: Chao Yu --- Daeho, Jaegeuk, Could you please check whether we could add this new field to struct f2fs_comp_option? so we can expand to allow user to query/config more options of compressed inode via new ioctl. It needs to consider before original patches goes to merge window, let me know you have other concerns. fs/f2fs/file.c | 1 + include/uapi/linux/f2fs.h | 1 + 2 files changed, 2 insertions(+) diff --git a/fs/f2fs/file.c b/fs/f2fs/file.c index 16ea10f2bcf5..fbf06311c88d 100644 --- a/fs/f2fs/file.c +++ b/fs/f2fs/file.c @@ -3965,6 +3965,7 @@ static int f2fs_ioc_get_compress_option(struct file *filp, unsigned long arg) option.algorithm = F2FS_I(inode)->i_compress_algorithm; option.log_cluster_size = F2FS_I(inode)->i_log_cluster_size; + option.compress_flag = F2FS_I(inode)->i_compress_flag; inode_unlock_shared(inode); diff --git a/include/uapi/linux/f2fs.h b/include/uapi/linux/f2fs.h index 352a822d4370..2b9c4c99ceee 100644 --- a/include/uapi/linux/f2fs.h +++ b/include/uapi/linux/f2fs.h @@ -93,6 +93,7 @@ struct f2fs_sectrim_range { struct f2fs_comp_option { __u8 algorithm; __u8 log_cluster_size; + __u16 compress_flag; }; #endif /* _UAPI_LINUX_F2FS_H */ -- 2.29.2
