Commit Message

config: Fix data race reported in cgroup_config_insert_into_mount_table

Fix the following data race issue reported by Coverity:

CID 465888: (#1 of 1): Check of thread-shared field evades lock
acquisition (LOCK_EVASION):

"The data guarded by this critical section may be read while in an
inconsistent state or modified by multiple racing threads.

In cgroup_config_insert_into_mount_table: Checking the value of a
thread-shared field outside of a locked region to determine if a locked
operation involving that thread shared field has completed."

Fix it by moving the config_table_index value check too under the
config_table_lock.
