Subject: os/bluestore/bluefs: Sync BlueFS log with its allocation delta
X-Git-Tag: v17.1.0~204^2~1
X-Git-Url: http://git.apps.os.sepia.ceph.com/?a=commitdiff_plain;h=ae5c5b7655535887ef56c96af62a1bf99f4c1d13;p=ceph.git

os/bluestore/bluefs: Sync BlueFS log with its allocation delta

BlueFS log is the only file that we can append to.
When we append to file we must take into consideration previously commited allocations,
otherwise update will be miscalculated.
