2018-01-25dd: add 'fullblock' iflagNicholas Clark

2018-01-24ash: add support for command_not_found_handle hook function (bashism)William Pitcock
This implements support for the command_not_found_handle hook function, which is useful for allowing package managers to suggest packages which could provide the command. Unlike bash, however, we ignore exit codes from the hook function and always return the correct POSIX error code (EX_NOTFOUND). function old new delta find_command 911 990 +79 Signed-off-by: William Pitcock <nenolod@dereferenced.org> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2018-01-19volume_id: add LittleFS detectionSven-Göran Bergh
Add support for LittleFS to blkid. Not included if FEATURE_BLKID_TYPE is not selected (neither UUID nor label). LittleFS is a small fail-safe filesystem designed for embedded systems. It has strong copy-on-write guarantees and storage on disk is always kept in a valid state. It also provides a form of dynamic wear levelling for systems that can not fit a full flash translation layer. (https://github.com/geky/littlefs) ARM has introduced it in its Mbed OS 5.7, so it starts to gain focus.
