Prevent NULL pointer dereference in blkg_tryget() on EL8 kernels blkg_tryget() as shipped in EL8 kernels does not seem to handle NULL @blkg as input; this is different from its mainline counterpart where NULL is accepted. To prevent dereferencing a NULL pointer when dealing with block devices which do not set a root_blkg on the request queue perform the NULL check in vdev_bio_associate_blkg().

Reorganize zfs(8) man page into sections Most subcommands got their own manpages (e.g. create). Some related commands grouped into a single manpage and symlinks created (e.g. set, get, and inherit). I did this when topics were either too short to warrant their own file or so interrelated that a user would want to refer between commands in the same file. Corrected .Sx internal references to .Xr cross refs; lots of .Sx references from when text was all in zfs.8 needed to be changed to .Xr zfs-$SUBCOMMAND 8 cross references. Divided subcommand list in zfs(8) into sections of related functionality. This required writing new descriptions for some commands. Preserved ".Os Linux", `.Os` macro parsing behavior differs between mandoc from the "BSD" mandoc package (available on Ubuntu) and man from Ubuntu's man-db package, which calls groff to format the manpages. Groff handles the `.Os` macro differently and wrongly, defaulting it to "BSD" in `/usr/share/groff/*/tmac/mdoc/doc-common`, instead of getting the default from `uname`. A future set of changes will introduce build-time preprocessing of manpages for platform-specific documentation and can insert the correct operating system name. Added SEE ALSO sections, the newly-divided zfs-*.8 subcommand man pages needed their own SEE ALSO sections pointing to related subcommands and, in some cases, documentation from other packages (e.g. zfs-share.8).

Add wrapper stub for zfs_cmd ioctl to libzpool FreeBSD needs a wrapper for handling zfs_cmd ioctls. In libzfs this is handled by zfs_ioctl. However, here we need to wrap the call directly.

Linux compat: Minimum kernel version 3.10 Increase the minimum supported kernel version from 2.6.32 to 3.10. This removes support for the following Linux enterprise distributions. Distribution | Kernel | End of Life ---------------- | ------ | ------------- Ubuntu 12.04 LTS | 3.2 | Apr 28, 2017 SLES 11 | 3.0 | Mar 32, 2019 RHEL / CentOS 6 | 2.6.32 | Nov 30, 2020 The following changes were made as part of removing support. * Updated `configure` to enforce a minimum kernel version as specified in the META file (Linux-Minimum: 3.10). configure: error: *** Cannot build against kernel version 2.6.32. *** The minimum supported kernel version is 3.10. * Removed all `configure` kABI checks and matching C code for interfaces which solely predate the Linux 3.10 kernel. * Updated all `configure` kABI checks to fail when an interface is missing which was in the 3.10 kernel up to the latest 5.1 kernel. Removed the HAVE_* preprocessor defines for these checks and updated the code to unconditionally use the verified interface. * Inverted the detection logic in several kABI checks to match the new interface as it appears in 3.10 and newer and not the legacy interface. * Consolidated the following checks in to individual files. Due the large number of changes in the checks it made sense to handle this now. It would be desirable to group other related checks in the same fashion, but this as left as future work. - config/kernel-blkdev.m4 - Block device kABI checks - config/kernel-blk-queue.m4 - Block queue kABI checks - config/kernel-bio.m4 - Bio interface kABI checks * Removed the kABI checks for sops->nr_cached_objects() and sops->free_cached_objects(). These interfaces are currently unused. Signed-off-by: Brian Behlendorf <behlendorf1@llnl.gov> Closes #9566 |

Make use of kvmalloc if available and fix vmem_alloc implementation This patch implements use of kvmalloc for GFP_KERNEL allocations, which may increase performance if the allocator is able to allocate physical memory, if kvmalloc is available as a public kernel interface (since v4.12). Otherwise it will simply fall back to virtual memory (vmalloc). Also fix vmem_alloc implementation which can lead to slow allocations since the first attempt with kmalloc does not make use of the noretry flag but tells the linux kernel to retry several times before it fails.
