| |
When building with Clang we encounter these warnings: | drivers/target/iscsi/iscsi_target_login.c:719:24: error: format | specifies type 'unsigned short' but the argument has type 'int' | [-Werror,-Wformat] " from node: %s\n", atomic_read(&sess->nconn), - | drivers/target/iscsi/iscsi_target_login.c:767:12: error: format | specifies type 'unsigned short' but the argument has type 'int' | [-Werror,-Wformat] " %s\n", atomic_read(&sess->nconn),
For both warnings, the format specifier is `%hu` which describes an unsigned short. The resulting type of atomic_read is an int. The proposed fix is to listen to Clang and swap the format specifier.
