[PATCH 01/10] ceph: honor AT_STATX_DONT_SYNC

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The description of this flag says "Don't sync attributes with the server".
In other words: always use the attributes cached in the kernel and don't
send network or local messages to refresh the attributes.
