Subject: os/bluestore: add flag to identify scrub IO
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=401cffadaf69749a298ceccc8f6291a72cdb5b65;p=ceph.git

os/bluestore: add flag to identify scrub IO

This commit introduces a new operation flag `CEPH_OSD_OP_FLAG_SCRUB` to explicitly
mark requests originating from scrub or deep-scrub workflows.
The flag allows BlueStore to differentiate scrub IO from normal operations.
