Variable Documentation

unsigned int ecryptfs_message_buf_len = ECRYPTFS_DEFAULT_MSG_CTX_ELEMS

Module parameter that defines the number of message buffer elements

Definition at line 55 of file main.c.

signed long ecryptfs_message_wait_timeout = ECRYPTFS_MAX_MSG_CTX_TTL / HZ

Module parameter that defines the maximum guaranteed amount of time to wait for a response from ecryptfsd. The actual sleep time will be, more than likely, a small amount greater than this specified value, but only less if the message successfully arrives.

Definition at line 67 of file main.c.

unsigned int ecryptfs_number_of_users = ECRYPTFS_DEFAULT_NUM_USERS

Module parameter that is an estimate of the maximum number of users that will be concurrently using eCryptfs. Set this to the right value to balance performance and memory use.
