Subject: [PATCH 0/6] ubi: remove character device flag from static volumes
Date: Fri, 25 Nov 2016 09:06:01 +0100 [thread overview]
Message-ID: <1480061167-21590-1-git-send-email-t.remmet@phytec.de> (raw)
Instead of marking static volume device files as character devices
introduced a truncate callback for device files.
This makes it possible to dump static ubi volumes from flash.
Teresa Remmet (6):
libfile: copy_file: Only open regular files with O_TRUNC
devfs: Add optional truncate callback for device files
ubi: Add truncate callback
fs: Remove O_TRUNC check for devices when open files
commands: ubi: ubiupdatevol: Open device with O_TRUNC
ubi: barebox: Remove character device flag from static volumes
