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.

This option allows to explicitly choose which compressions, if any,
|
|
are enabled in UBIFS. Removing compressors means inability to read
|
|
existing file systems.

If unsure, say 'N'.

LZO compressor is generally faster than zlib but compresses worse.

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'

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.
