ChangeSet 1.1143.1.1, 2003/03/19 11:21:52-08:00, [EMAIL PROTECTED]
[PATCH] USB: fix to synchronous API regarding memory allocation
some part of the synchronous API is used in the block io error handling
code paths. Therefore it may use only GFP_NOIO, not GFP_KERNEL.
- avoid deadlock due to wrong memory allocation in block io path
