LZO compressor is generally faster than zlib but compresses worse.

ubifs: introduce UBIFS_ATIME_SUPPORT to ubifs To make ubifs support atime flexily, this commit introduces a Kconfig option named as UBIFS_ATIME_SUPPORT. With UBIFS_ATIME_SUPPORT=n: ubifs keeps the full compatibility to no_atime from the start of ubifs. =================UBIFS_ATIME_SUPPORT=n======================= -o - no atime -o atime - no atime -o noatime - no atime -o relatime - no atime -o strictatime - no atime -o lazyatime - no atime With UBIFS_ATIME_SUPPORT=y: ubifs supports the atime same with other main stream file systems. =================UBIFS_ATIME_SUPPORT=y======================= -o - default behavior (relatime currently) -o atime - atime support -o noatime - no atime support -o relatime - relative atime support -o strictatime - strict atime support -o lazyatime - lazy atime support Signed-off-by: Dongsheng Yang <yangds.fnst@cn.fujitsu.com> Reviewed-by: Richard Weinberger <richard@nod.at> Signed-off-by: Richard Weinberger <richard@nod.at>

help
Originally UBIFS did not support atime, because it looked like a bad idea due
increased flash wear. This option adds atime support and it is disabled by default
to preserve the old behavior. If you enable this option, UBIFS starts updating atime,
which means that file-system read operations will cause writes (inode atime
updates). This may affect file-system performance and increase flash device wear,
so be careful. How often atime is updated depends on the selected strategy:
strictatime is the "heavy", relatime is "lighter", etc.
If unsure, say 'N'

ubifs: add CONFIG_BLOCK dependency for encryption This came up during the v4.10 merge window: warning: (UBIFS_FS_ENCRYPTION) selects FS_ENCRYPTION which has unmet direct dependencies (BLOCK) fs/crypto/crypto.c: In function 'fscrypt_zeroout_range': fs/crypto/crypto.c:355:9: error: implicit declaration of function 'bio_alloc';did you mean 'd_alloc'? [-Werror=implicit-function-declaration] bio = bio_alloc(GFP_NOWAIT, 1); The easiest way out is to limit UBIFS_FS_ENCRYPTION to configurations that also enable BLOCK.

Enable encryption of UBIFS files and directories. This
feature is similar to ecryptfs, but it is more memory
efficient since it avoids caching the encrypted and
decrypted pages in the page cache.
ubifs: Add CONFIG_UBIFS_FS_SECURITY to disable/enable security labels When write syscall is called, every time security label is searched to determine that file's privileges should be changed. If LSM(Linux Security Model) is not used, this is useless. So introduce CONFIG_UBIFS_SECURITY to disable security labels. it's default value is "y".

bool "UBIFS Security Labels"
depends on UBIFS_FS

help
Security labels provide an access control facility to support Linux
Security Models (LSMs) accepted by AppArmor, SELinux, Smack and TOMOYO
Linux. This option enables an extended attribute handler for file
security labels in the ubifs filesystem, so that it requires enabling
the extended attribute support in advance.
If you are not using a security module, say N.
