Since we don't need to maintain large pools of messages, we can just use the standard mempool_t. We maintain a msgpool 'wrapper' because we need the mempool_t* in the alloc function, and mempool gives us only pool_data. Signed-off-by:

ceph_sb_to_client and ceph_client are really identical, we need to dump one; while function ceph_client is confusing with "struct ceph_client", ceph_sb_to_client's definition is more clear; so we'd better switch all call to ceph_sb_to_client. -static inline struct ceph_client *ceph_client(struct super_block *sb) -{ - return sb->s_fs_info; -} Signed-off-by:

If we abort a request, we return to caller, but the request may still complete. And if we hold the dir FILE_EXCL bit, we may not release a lease when sending a request. A simple un-tar, control-c, un-tar again will reproduce the bug (manifested as a 'Cannot open: File exists'). Ensure we invalidate affected dentry leases (as well dir I_COMPLETE) so we don't have valid (but incorrect) leases. Do the same, consistently, at other sites where I_COMPLETE is similarly cleared.

When we abort requests we need to prevent fill_trace et al from doing anything that relies on locks held by the VFS caller. This fixes a race between the reply handler and the abort code, ensuring that continue holding the dir mutex until the reply handler completes. Signed-off-by:

We would occasionally BUG out in the reply handler because r_reply was nonzero, due to a race with ceph_mdsc_do_request temporarily setting r_reply to an ERR_PTR value. This is unnecessary, messy, and also wrong in the EIO case. Clean up by consistently using r_err for errors and r_reply for messages. Also fix the abort logic to trigger consistently for all errors that return to the caller early (e.g., EIO from timeout case). If an abort races with a reply, use the result from the reply. Also fix locking for r_err, r_reply update in the reply handler. Signed-off-by:

Now we have a set of nested attributes: IFLA_VFINFO_LIST (NESTED) IFLA_VF_INFO (NESTED) IFLA_VF_MAC IFLA_VF_VLAN IFLA_VF_TX_RATE This allows a single set to operate on multiple attributes if desired. Among other things, it means a dump can be replayed to set state. The current interface has yet to be released, so this seems like something to consider for 2.6.34. Signed-off-by:

TCP MD5 support uses percpu data for temporary storage. It currently disables preemption so that same storage cannot be reclaimed by another thread on same cpu. We also have to make sure a softirq handler wont try to use also same context. Various bug reports demonstrated corruptions. Fix is to disable preemption and BH. Reported-by:

In the FPU emulator code of the MIPS, the Cause bits of the FCSR register are not currently writeable by the ctc1 instruction. In odd corner cases, this can cause problems. For example, a case existed where a divide-by-zero exception was generated by the FPU, and the signal handler attempted to restore the FPU registers to their state before the exception occurred. In this particular setup, writing the old value to the FCSR register would cause another divide-by-zero exception to occur immediately. The solution is to change the ctc1 instruction emulator code to allow the Cause bits of the FCSR register to be writeable. This is the behaviour of the hardware that the code is emulating. This problem was found by Shane McDonald, but the credit for the fix goes to Kevin Kissell. In Kevin's words: I submit that the bug is indeed in that ctc_op: case of the emulator. The Cause bits (17:12) are supposed to be writable by that instruction, but the CTC1 emulation won't let them be updated by the instruction. I think that actually if you just completely removed lines 387-388 [...] things would work a good deal better. At least, it would be a more accurate emulation of the architecturally defined FPU. If I wanted to be really, really pedantic (which I sometimes do), I'd also protect the reserved bits that aren't necessarily writable. Signed-off-by:
