We already have the helper, we can convert the rest of the kernel mechanically using: git grep -l 'atomic_inc_not_zero.*mm_users' | xargs sed -i 's/atomic_inc_not_zero(&\(.*\)->mm_users)/mmget_not_zero\(\1\)/' This is needed for a later patch that hooks into the helper, but might be a worthwhile cleanup on its own.

Now that %z is standartised in C99 there is no reason to support %Z. Unlike %L it doesn't even make format strings smaller. Use BUILD_BUG_ON in a couple ATM drivers.

In case if epoll_ctl is called with operation EPOLL_CTL_DEL then @epds.events variable allocated on stack may contain random bits which we test then for EPOLLEXCLUSIVE. Since currently the test look like if (epds.events & EPOLLEXCLUSIVE) { if (op == EPOLL_CTL_MOD) goto error_tgt_fput; if (op == EPOLL_CTL_ADD && (is_file_epoll(tf.file) || (epds.events & ~EPOLLEXCLUSIVE_OK_BITS))) goto error_tgt_fput; } Nothing serious will happen even if epds.events has this bit set, still better to be on safe side and make sure that we're to test this bit at all.

Currently all the p_paddr of PT_LOAD headers are assigned to 0, which is not true and could be misleading, since 0 is a valid physical address. User space tools like makedumpfile needs to know physical address for PT_LOAD segments of direct mapped regions. Therefore this patch updates paddr for such regions. It also sets an invalid paddr (-1) for other regions, so that user space tool can know whether a physical address provided in PT_LOAD is correct or not. I do not know why it was 0, which is a valid physical address. But certainly, it might break some user space tools, and those need to be fixed. For example, see following code from kexec-tools kexec/kexec-elf.c:build_mem_phdrs() if ((phdr->p_paddr + phdr->p_memsz) < phdr->p_paddr) { /* The memory address wraps */ if (probe_debug) { fprintf(stderr, "ELF address wrap around\n"); } return -1; } We do not need to perform above check for an invalid physical address. I think, kexec-tools and makedumpfile will need fixup. I already have those fixup which will be sent upstream once this patch makes through. Pro with this approach is that, it will help to calculate variable like page_offset, phys_base from PT_LOAD even when they are randomized and therefore will reduce many variable and version specific values in user space tools. Having an ASLR offset information can help to translate an identity mapped virtual address to a physical address. But that would be an additional field in PT_LOAD header structure and an arch dependent value. Moreover, sending a valid physical address like 0 does not seem right. So, IMHO it is better to fix that and send valid physical address when available (identity mapped).

GUI environments seem to be becoming more agressive at scanning filesystems, to the point where autofs cannot expire mounts at all. This is one key reason the update of the autofs dentry info last_used field is done in the expire system when the dentry is seen to be in use. But somewhere along the way instances of the update has crept back into the autofs path walk functions which, with the more aggressive file access patterns, is preventing expiration. Changing the update in the path walk functions allows autofs to at least make progress in spite of frequent immediate re-mounts from file accesses.

由 Masato Suzuki 提交于
The introduction of the multi-device feature partially broke the support for zoned block devices. In the function f2fs_scan_devices, sbi->devs allocation and initialization is skipped in the case of a single device mount. This result in no device information structure being allocated for the device. This is fine if the device is a regular device, but in the case of a zoned block device, the device zone type array is not initialized, which causes the function __f2fs_issue_discard_zone to fail as get_blkz_type is unable to determine the zone type of a section. Fix this by always allocating and initializing the sbi->devs device information array even in the case of a single device if that device is zoned. For this particular case, make sure to obtain a reference on the single device so that the call to blkdev_put() in destroy_device_list operates as expected.

In scenario of intensively node allocation, free nids will be ran out soon, then it needs to stop to load free nids by traversing NAT blocks, in worse case, if NAT blocks does not be cached in memory, it generates IOs which slows down our foreground operations. In order to speed up node allocation, in this patch we introduce a new free_nid_bitmap array, so there is an bitmap table for each NAT block, Once the NAT block is loaded, related bitmap cache will be switched on, and bitmap will be set during traversing nat entries in NAT block, later we can query and update nid usage status in memory completely. With such implementation, I expect performance of node allocation can be improved in the long-term after filesystem image is mounted.
