Subject: ceph: avoid immediate cap check after import
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7e57b81c7688c762bc9e775bc83f9fc17946f527;p=linux-beck.git

ceph: avoid immediate cap check after import

The NODELAY flag avoids the heuristics that delay cap (issued/wanted)
release.  There's no reason for that after we import a cap, and it kills
whatever benefit we get from those delays.
