Check return value in the Gluster driver for fcntl, as pointed
|
|
|
9ae3a8 |
out by coverity.
|
|
|
9ae3a8 |
|
|
|
9ae3a8 |
Cleanup of s->fds is done inline in the error handling for the fcntl()
|
|
|
9ae3a8 |
call, rather than in the function cleanup, to keep changes minimal for
|
|
|
9ae3a8 |
future backports.
|
|
|
9ae3a8 |
|
|
|
9ae3a8 |
Downstream-only, as upstream Gluster driver does not use fcntl anymore.
