abdullah alamoudi has uploaded a new patch set (#2). Change subject: [NO ISSUE][STO] Fix deadlock in buffer cache ......................................................................
[NO ISSUE][STO] Fix deadlock in buffer cache - user model changes: no - storage format changes: no - interface changes: no details: - When two threads concurrently attempt to pin a page, one as a new page, the other as an existing page, a deadlock might happen. - The deadlock is caused by the reader as a new page setting the valid flag before the ReaderThread attempts to read the page. - The fix is to have the reader thread ignore the read request and have the reader as a new page notify all the other readers that the page is valid.
