2016-07-27Disable "frame-address" warningLinus Torvalds1-0/+1
Newer versions of gcc warn about the use of __builtin_return_address() with a non-zero argument when "-Wall" is specified: kernel/trace/trace_irqsoff.c: In function ‘stop_critical_timings’: kernel/trace/trace_irqsoff.c:433:86: warning: calling ‘__builtin_return_address’ with a nonzero argument is unsafe [-Wframe-address] stop_critical_timing(CALLER_ADDR0, CALLER_ADDR1); [ .. repeats a few times for other similar cases .. ] It is true that a non-zero argument is somewhat dangerous, and we do not actually have very many uses of that in the kernel - but the ftrace code does use it, and as Stephen Rostedt says: "We are well aware of the danger of using __builtin_return_address() of > 0. In fact that's part of the reason for having the "thunk" code in x86 (See arch/x86/entry/thunk_{64,32}.S). [..] it adds extra frames when tracking irqs off sections, to prevent __builtin_return_address() from accessing bad areas. In fact the thunk_32.S states: 'Trampoline to trace irqs off. (otherwise CALLER_ADDR1 might crash)'." For now, __builtin_return_address() with a non-zero argument is the best we can do, and the warning is not helpful and can end up making people miss other warnings for real problems. So disable the frame-address warning on compilers that need it. Acked-by: Steven Rostedt <[email protected]> Signed-off-by: Linus Torvalds <[email protected]>
2016-07-28ceph: Correctly return NXIO errors from ceph_llseekPhil Turnbull1-7/+5
ceph_llseek does not correctly return NXIO errors because the 'out' path always returns 'offset'. Fixes: 06222e491e66 ("fs: handle SEEK_HOLE/SEEK_DATA properly in all fs's that define their own llseek") Signed-off-by: Phil Turnbull <[email protected]> Signed-off-by: Yan, Zheng <[email protected]>
2016-07-28ceph: Mark the file cache as unreclaimableNikolay Borisov1-2/+2
Ceph creates multiple caches with the SLAB_RECLAIMABLE flag set, so that it can satisfy its internal needs. Inspecting the code shows that most of the caches are indeed reclaimable since they are directly related to the generic inode/dentry shrinkers. However, one of the cache used to satisfy struct file is not reclaimable since its entries are freed only when the last reference to the file is dropped. If a heavily loaded node opens a lot of files it can introduce non-trivial discrepancies between memory shown as reclaimable and what is actually reclaimed when drop_caches is used. Fix this by removing the reclaimable flag for the file's cache. Signed-off-by: Nikolay Borisov <[email protected]> Signed-off-by: Yan, Zheng <[email protected]>
2016-07-28ceph: optimize cap flush waitingYan, Zheng3-27/+73
Add a 'wake' flag to ceph_cap_flush struct, which indicates if there is someone waiting for it to finish. When getting flush ack message, we check the 'wake' flag in corresponding ceph_cap_flush struct to decide if we should wake up waiters. One corner case is that the acked cap flush has 'wake' flags is set, but it is not the first one on the flushing list. We do not wake up waiters in this case, set 'wake' flags of preceding ceph_cap_flush struct instead Signed-off-by: Yan, Zheng <[email protected]>
2016-07-28ceph: cleanup ceph_flush_snaps()Yan, Zheng3-88/+105
This patch devide __ceph_flush_snaps() into two stags. In the first stage, __ceph_flush_snaps() assign snapcaps flush TIDs and add them to cap flush lists. __ceph_flush_snaps() keeps holding the i_ceph_lock in this stagge. So inode's auth cap can not change. In the second stage, __ceph_flush_snaps() send flushsnap cap messages. i_ceph_lock is unlocked before sending each cap message. If auth cap changes in the middle, __ceph_flush_snaps() just stops. This is OK because kick_flushing_inode_caps() will re-send flushsnap cap messages to inode's new auth MDS.

2016-07-28ceph: kick cap flushes before sending other cap messageYan, Zheng1-9/+34

2016-07-28ceph: unify cap flush and snapcap flushYan, Zheng5-222/+175
This patch includes following changes - Assign flush tid to snapcap flush - Remove session's s_cap_snaps_flushing list. Add inode to session's s_cap_flushing list instead. Inode is removed from the list when there is no pending snapcap flush or cap flush. - make __kick_flushing_caps() re-send both snapcap flushes and cap flushes.

2016-07-28ceph: use list instead of rbtree to track cap flushesYan, Zheng5-118/+56

2016-07-28ceph: allow dentry_lease_is_valid to work under RCU walkJeff Layton1-15/+26
Under rcuwalk, we need to take extra care when dereferencing d_parent. We want to do that once and pass a pointer to dentry_lease_is_valid. Also, we must ensure that that function can handle the case where we're racing with d_release. Check whether "di" is NULL under the d_lock, and just return 0 if so. Finally, we still need to kick off a renewal job if the lease is getting close to expiration. If that's the case, then just drop out of rcuwalk mode since that could block.

2016-07-28ceph: clear d_fsinfo pointer under d_lockJeff Layton1-1/+5
To check for a valid dentry lease, we need to get at the ceph_dentry_info. Under rcuwalk though, we may end up with a dentry that is on its way to destruction. Since we need to take the d_lock in dentry_lease_is_valid already, we can just ensure that we clear the d_fsinfo pointer out under the same lock before destroying it.

On pre-Niagara systems, we fetch the fault address on data TLB exceptions from the TLB_TAG_ACCESS register. But this register also contains the context ID assosciated with the fault in the low 13 bits of the register value. This propagates into current_thread_info()->fault_address and can cause trouble later on. So clear the low 13-bits out of the TLB_TAG_ACCESS value in the cases where it matters.

2016-07-27Disable "maybe-uninitialized" warning globallyLinus Torvalds3-10/+5
Several build configurations had already disabled this warning because it generates a lot of false positives. But some had not, and it was still enabled for "allmodconfig" builds, for example. Looking at the warnings produced, every single one I looked at was a false positive, and the warnings are frequent enough (and big enough) that they can easily hide real problems that you don't notice in the noise generated by -Wmaybe-uninitialized. The warning is good in theory, but this is a classic case of a warning that causes more problems than the warning can solve. If gcc gets better at avoiding false positives, we may be able to re-enable this warning. But as is, we're better off without it, and I want to be able to see the *real* warnings.
