BUG 2242121: cephfs: safeguard localClusterState struct from race conditions #191
BUG 2242121: cephfs: safeguard localClusterState struct from race conditions #191
Conversation
Multiple go-routines may simultaneously check for a clusterID's presence in clusterAdditionalInfo and create an entry if it is absent. This set of operation needs to be serialized. Therefore, this commit safeguards clusterAdditionalInfo map from concurrent writes with a mutex to prevent the above problem. Signed-off-by: Rakshith R <[email protected]> (cherry picked from commit 82f1323)
Multiple go-routines may simultaneously create the subVolumeGroupCreated map or write into it for a particular group. This commit safeguards subVolumeGroupCreated map from concurrent creation/writes while allowing for multiple readers. Signed-off-by: Rakshith R <[email protected]> (cherry picked from commit d516a1d)
