Patch series "second round of tracepoints for DAX". This second round of DAX tracepoint patches adds tracing to the PTE fault path (dax_iomap_pte_fault(), dax_pfn_mkwrite(), dax_load_hole(), dax_insert_mapping()) and to the writeback path (dax_writeback_mapping_range(), dax_writeback_one()). The purpose of this tracing is to give us a high level view of what DAX is doing, whether faults are being serviced by PMDs or PTEs, and by real storage or by zero pages covering holes. I do have some patches nearly ready which also add tracing to grab_mapping_entry() and dax_insert_mapping_entry(). These are more targeted at logging how we are interacting with the radix tree, how we use empty entries for locking, whether we "downgrade" huge zero pages to 4k PTE sized allocations, etc. In the end it seemed to me that this might be too detailed to have as constantly present tracepoints, but if anyone sees value in having tracepoints like this in the DAX code permanently (Jan?), please let me know and I'll add those last two patches. All these tracepoints were done to be consistent with the style of the XFS tracepoints and with the existing DAX PMD tracepoints. This patch (of 6): Add tracepoints to dax_iomap_pte_fault(), following the same logging conventions as the rest of DAX. Here is an example fault that initially tries to be serviced by the PMD fault handler but which falls back to PTEs because the VMA isn't large enough to hold a PMD: small-1086 [005] .... 71.140014: xfs_filemap_huge_fault: dev 259:0 ino 0x1003 small-1086 [005] .... 71.140027: dax_pmd_fault: dev 259:0 ino 0x1003 shared WRITE|ALLOW_RETRY|KILLABLE|USER address 0x10420000 vm_start 0x10200000 vm_end 0x10500000 pgoff 0x220 max_pgoff 0x1400 small-1086 [005] .... 71.140028: dax_pmd_fault_done: dev 259:0 ino 0x1003 shared WRITE|ALLOW_RETRY|KILLABLE|USER address 0x10420000 vm_start 0x10200000 vm_end 0x10500000 pgoff 0x220 max_pgoff 0x1400 FALLBACK small-1086 [005] .... 71.140035: dax_pte_fault: dev 259:0 ino 0x1003 shared WRITE|ALLOW_RETRY|KILLABLE|USER address 0x10420000 pgoff 0x220 small-1086 [005] .... 71.140396: dax_pte_fault_done: dev 259:0 ino 0x1003 shared WRITE|ALLOW_RETRY|KILLABLE|USER address 0x10420000 pgoff 0x220 MAJOR|NOPAGE Link: http://lkml.kernel.org/r/20170221195116.13278-2-ross.zwisler@linux.intel.comSigned-off-by:Ross Zwisler <ross.zwisler@linux.intel.com> Reviewed-by:

The previous patch ("mm: prevent potential recursive reclaim due to clearing PF_MEMALLOC") has shown that simply setting and clearing PF_MEMALLOC in current->flags can result in wrongly clearing a pre-existing PF_MEMALLOC flag and potentially lead to recursive reclaim. Let's introduce helpers that support proper nesting by saving the previous stat of the flag, similar to the existing memalloc_noio_* and memalloc_nofs_* helpers. Convert existing setting/clearing of PF_MEMALLOC within mm to the new helpers. There are no known issues with the converted code, but the change makes it more robust.

Patch series "more robust PF_MEMALLOC handling" This series aims to unify the setting and clearing of PF_MEMALLOC, which prevents recursive reclaim. There are some places that clear the flag unconditionally from current->flags, which may result in clearing a pre-existing flag. This already resulted in a bug report that Patch 1 fixes (without the new helpers, to make backporting easier). Patch 2 introduces the new helpers, modelled after existing memalloc_noio_* and memalloc_nofs_* helpers, and converts mm core to use them. Patches 3 and 4 convert non-mm code. This patch (of 4): __alloc_pages_direct_compact() sets PF_MEMALLOC to prevent deadlock during page migration by lock_page() (see the comment in __unmap_and_move()). Then it unconditionally clears the flag, which can clear a pre-existing PF_MEMALLOC flag and result in recursive reclaim. This was not a problem until commit a8161d1e ("mm, page_alloc: restructure direct compaction handling in slowpath"), because direct compation was called only after direct reclaim, which was skipped when PF_MEMALLOC flag was set. Even now it's only a theoretical issue, as the new callsite of __alloc_pages_direct_compact() is reached only for costly orders and when gfp_pfmemalloc_allowed() is true, which means either __GFP_NOMEMALLOC is in gfp_flags or in_interrupt() is true. There is no such known context, but let's play it safe and make __alloc_pages_direct_compact() robust for cases where PF_MEMALLOC is already set.

Although all architectures use a deposited page table for THP on anonymous VMAs, some architectures (s390 and powerpc) require the deposited storage even for file backed VMAs due to quirks of their MMUs. This patch adds support for depositing a table in DAX PMD fault handling path for archs that require it. Other architectures should see no functional changes.

Depending on the flags of the PMD being zapped there may or may not be a deposited pgtable to be freed. In two of the three cases this is open coded while the third uses the zap_deposited_table() helper. This patch converts the others to use the helper to clean things up a bit.

CURRENT_TIME_SEC is not y2038 safe. current_time() will be transitioned to use 64 bit time along with vfs in a separate patch. There is no plan to transition CURRENT_TIME_SEC to use y2038 safe time interfaces. current_time() returns timestamps according to the granularities set in the inode's super_block. The granularity check to call current_fs_time() or CURRENT_TIME_SEC is not required. Use current_time() directly to update inode timestamp. Use timespec_trunc during file system creation, before the first inode is created. Link: http://lkml.kernel.org/r/1491613030-11599-9-git-send-email-deepa.kernel@gmail.comSigned-off-by:

CURRENT_TIME is not y2038 safe. The macro will be deleted and all the references to it will be replaced by ktime_get_* apis. struct timespec is also not y2038 safe. Retain timespec for timestamp representation here as ceph uses it internally everywhere. These references will be changed to use struct timespec64 in a separate patch. The current_fs_time() api is being changed to use vfs struct inode* as an argument instead of struct super_block*. Set the new mds client request r_stamp field using ktime_get_real_ts() instead of using current_fs_time(). Also, since r_stamp is used as mtime on the server, use timespec_trunc() to truncate the timestamp, using the right granularity from the superblock. This api will be transitioned to be y2038 safe along with vfs. Link: http://lkml.kernel.org/r/1491613030-11599-5-git-send-email-deepa.kernel@gmail.comSigned-off-by:

CURRENT_TIME macro is not y2038 safe on 32 bit systems. The patch replaces all the uses of CURRENT_TIME by current_time() for filesystem times, and ktime_get_* functions for authentication timestamps and timezone calculations. This is also in preparation for the patch that transitions vfs timestamps to use 64 bit time and hence make them y2038 safe. CURRENT_TIME macro will be deleted before merging the aforementioned change. The inode timestamps read from the server are assumed to have correct granularity and range. The patch also assumes that the difference between server and client times lie in the range INT_MIN..INT_MAX. This is valid because this is the difference between current times between server and client, and the largest timezone difference is in the range of one day. All cifs timestamps currently use timespec representation internally. Authentication and timezone timestamps can also be transitioned into using timespec64 when all other timestamps for cifs is transitioned to use timespec64.

While examining output from trial builds with -Wformat-security enabled, many strings were found that should be defined as "const", or as a char array instead of char pointer. This makes some static analysis easier, by producing fewer false positives. As these are all trivial changes, it seemed best to put them all in a single patch rather than chopping them up per maintainer.

Commit afddba49 ("fs: introduce write_begin, write_end, and perform_write aops") introduced AOP_FLAG_UNINTERRUPTIBLE flag which was checked in pagecache_write_begin(), but that check was removed by 4e02ed4b ("fs: remove prepare_write/commit_write"). Between these two commits, commit d9414774 ("cifs: Convert cifs to new aops.") added a check in cifs_write_begin(), but that check was soon removed by commit a98ee8c1 ("[CIFS] fix regression in cifs_write_begin/cifs_write_end"). Therefore, AOP_FLAG_UNINTERRUPTIBLE flag is checked nowhere. Let's remove this flag. This patch has no functionality changes.

Patch series "set_memory_* functions header refactor", v3. The set_memory_* APIs came out of a desire to have a better way to change memory attributes. Many of these attributes were linked to cache functionality so the prototypes were put in cacheflush.h. These days, the APIs have grown and have a much wider use than just cache APIs. To support this growth, split off set_memory_* and friends into a separate header file to avoid growing cacheflush.h for APIs that have nothing to do with caches.
