Subject: [PATCH 288/297] cluster/ec: Fix coverity issues |
|
|
|
Fixed the following coverity issue in both flush/fsync |
|
>>> CID 1404964: Null pointer dereferences (REVERSE_INULL) |
|
>>> Null-checking "fd" suggests that it may be null, but it has already |
|
been dereferenced on all paths leading to the check. |
|
>>> if (fd != NULL) { |
|
>>> fop->fd = fd_ref(fd); |
|
>>> if (fop->fd == NULL) { |
|
>>> gf_msg(this->name, GF_LOG_ERROR, 0, |
|
>>> "Failed to reference a " |
|
>>> "file descriptor."); |
|
