We created a 64bit SLES11 SP1 guest, and then used a script to change memory (using mem-set command) periodically (in 1 second): set 1G, set 2G, set 1G, set 2G, and so on. After a few minutes, we encountered QEMU exit due to SIGBUS error. Below is the call trace captured by gdb: The call trace: Program received signal SIGBUS, Bus error. 0x00007f94f74773d7 in memcpy () from /lib64/libc.so.6 (gdb)

The usage of the centralized bitops in com32/lib/vsscanf.c is not correct because the bitmap that we're accessing is too large for the 'bt', 'bts' and 'btc' instructions to

Currently the process of dlm join contains 2 steps: query join and assert join. After query join, the joined node will set its joining_node. So if the joining node happens to panic before the 2nd step, the joined node will fail to clear its joining_node flag because that node isn't in the domain map. It at least cause 2 problems. 1. All the new join request will fail. So no new node can mount

Former logic of ocfs2_file_aio_write() was a bit stricky to unlock the rw_lock and i_alloc_sem, by using some private bits in struct 'iocb' to communite with ocfs2_dio_end_io(), it did work before we introduce the patch of supporting 'coherency=full,buffered' option, since rw_lock and i_alloc_sem were never acquired both at the same time, no mattar we doing buffered or direct IO or

We currently have this problem where you can truncate pages that have not yet been written for an ordered extent. We do this because the truncate will be coming behind to clean us up anyway so what''s the harm right? Well if truncate fails for whatever reason we leave an orphan item around for the file to be cleaned up later. But if the user goes and truncates up the file and tries to
