Subject: db: re-enable write support for v5 filesystems.
X-Git-Tag: v3.2.0-alpha2~15
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=d14bf4dda7f5a59ba3fbaed38cd829db5f68a105;p=thirdparty%2Fxfsprogs-dev.git

db: re-enable write support for v5 filesystems.

As we can now verify and recalculate CRCs on IO, we can modify the
on-disk structures without corrupting the filesyste, This makes it
safe to turn write support on for v5 filesystems for the first time.
