linux-2.4.21-s390-13-june2003-patches.tar.gz / MD5 ... per-problem-patches, recommended (2004-05-18)

These patches contain the following linux kernel bug fixes:

Description: iucv: restart of multiple IUCV connections fails.
Symptom: Further IUCV connections are only possible after reloading of module netiucv.
Problem: When restarting IUCV connections, the old IUCV pathids are not reused. Thus repeated restart of a single IUCV connection resp. few restarts of multiple IUCV connections result in reaching the maximum number limit of IUCV paths.
Solution: Handling of an IUCV connection severed by partner is changed: No reconnect is made; instead the IUCV connection stays in state STARTWAIT till a "Connection Pending" interrupt arrives.
Problem-ID: 7640

Description: kernel: mlock() gets stuck in get_user_pages/follow_page.
Symptom: Process doing mlock loops in the kernel with kernel locks held.
Problem: set_pte/pte_mkdirty does not cause pte_dirty to return true, but the common mm code relies on it.
Solution: Set page dirty if required but don't loop on !pte_dirty().
Problem-ID: 8210

Description: qeth: module use count problem in performance statistics.
Symptom: Negative qeth module use count.
Problem: Forgot to increase module counter when reading perf stats.
Solution: Call MOD_INC_USE_COUNT appropriately.
Problem-ID: 8394

Description: zfcp: zfcp logs a wrong message when trying to register a LUN which is already in use.
Symptom: If a LUN is already in use by another guest zfcp module says that there is no access to a LUN.
Problem: zfcp modules analyzes FSF status qualifier in a false order.
Solution: Let zfcp module analyze FSF status qualifier correctly.
Problem-ID: 7036
