These patches contain the following linux kernel bug fixes:
- Description:
- DASD driver sets improper default cache mode on ESS
- Symptom:
- Performance limitation.
- Problem:
- Suboptimal caching behavior for 'default' workload limits I/O performance.
- Solution:
- Set proper default (normal caching) and provide IOCTL "BIODASDGATTR" to get current setting.
- Problem-ID:
- 5409
- Description:
- Massive workload combined with ESS flascopy leading to I/O hang.
- Symptom:
- FlashCopy I/O hang
- Problem:
- State change interrupt handler checks only first request in cqr-queue, but in case the fastpath for start_IO was successful, it might happen that the second request is long busy.
- Solution:
- Check the whole cqr-queue for long busy.
- Problem-ID:
- 4676
- Description:
- Unnecessary restriction to length of inputdata for MEX request
- Symptom:
- errno = EINVAL for valid data
- Problem:
- checking for even inputdatalength for both CRT and MEX request
- Solution:
- only check for CRT request
- Problem-ID:
- 5633
Everybody should apply this patch.
