I think the problem is that we authpin anything we rdlock... is that really necessary?
- Target version set to v0.21
In order to change this, we need a way to wake up the replica waiter when we find out the auth changed, so we can resend the REQRDLOCK. e.g., in handle_export_notify(). there is no infrastructure for that right now.
also need to verify that we resend if we were exporting/importing, and/or the migration aborted. :/
- Target version changed from v0.21 to v0.22
- Status changed from New to In Progress
- % Done changed from 0 to 50
- % Done changed from 50 to 90
- Status changed from In Progress to Resolved

Sigh.. that was a bad decision. Reverted by commit:b7b77ffc1718ea1743e199745e2c55f99ddaa16a, although if we ever go back, a few fixes are in commit:5f6d524df7a20b2d3589226669129eea04739f51.
- Project changed from Ceph to CephFS
- Category deleted (
1)
- Target version deleted (
v0.22)
Bulk updating project=ceph category=mds bugs so that I can remove the MDS category from the Ceph project to avoid confusion.
