Harish Chegondi 04a646df12 IB/hfi1: Fix the bail out code in pin_vector_pages() function ... In pin_vector_pages() function, if there is any error while pinning the pages or while adding a pinned buffer to the cache, the bail out code needs to unpin any pinned pages that are not in the cache and adjust the n_locked counter that counts the total pages pinned. The current bail out code doesn't seem to be doing it right in two cases: 1. Before pinning required pages for a buffer, the SDMA pinned buffer cache is searched to see if the virtual address range that needs to be pinned is already pinned. If there isn't a hit in the cache, a new node is created for the buffer and is added to the cache after the buffer is pinned. If adding the new node to the cache fails, the n_locked count is decremented properly but the pinned pages are not freed. This commit fixes this issue. 2. If there is a hit in the SDMA cache, but the cached buffer doesn't have enough pages to cover the entire address range that needs to be pinned, the node for the cached buffer is extracted from the cache, remaining pages needed are pinned and added to the node. The node is finally added back into the cache. If there is an error pinning the extra pages, the bail out code frees all the pages in the node but the n_locked count is not being decremented by the no of pages in the node that are freed. This commit fixes this issue. This commit fixes the above two issues by creating a new function that frees the pages in a node and decrements the n_locked count by the number of pages freed.
