| Subject: SMB3: retry on STATUS_INSUFFICIENT_RESOURCES instead of failing write |
| |
| commit 8d526d62db907e786fd88948c75d1833d82bd80e upstream. |
| |
| Some servers such as Windows 10 will return STATUS_INSUFFICIENT_RESOURCES |
| as the number of simultaneous SMB3 requests grows (even though the client |
| has sufficient credits). Return EAGAIN on STATUS_INSUFFICIENT_RESOURCES |
| so that we can retry writes which fail with this status code. |
| |
| This (for example) fixes large file copies to Windows 10 on fast networks. |
