Allow to compress mmap files in commit e3c548323d32 ("f2fs: let's allow compression for mmap files"). However, we cannot set the compress option to the mmap file. To keep the same concept in both compress_modes, f2fs_ioc_set_compress_option should also allow it.Let's remove checking mmap files in f2fs_ioc_set_compress_option so that we can set compress option to the mmap files.
Could you please check below patch? https://lore.kernel.org/linux-f2fs-devel/20230529104709.2560779-1-c...@kernel.org Thanks,
