+ The Solaris Porting Layer (SPL) is a Linux kernel module which provides
+ many of the Solaris kernel APIs. This shim layer makes it possible to
+ run Solaris kernel code in the Linux kernel with relatively minimal
+ modification. The Solaris Porting LAyer Tests (SPLAT) is a Linux kernel
+ module which provides a testing harness for the SPL module.
+ .
+ SPL can be particularly useful when you want to track upstream Illumos
+ (or any other OpenSolaris fork) development closely and don't want the
+ overhead of maintaining a large patch which converts Solaris primitives
+ to Linux primitives.
+ .
+ This is a transitional dummy package. It can safely be removed.

+Contrary to initial testing we cannot rely on these kernels to

+Therefore, the kfpu_begin() and kfpu_end() functions have been
+updated to unconditionally save and restore the FPU state.

+Subject: [PATCH] Fix CONFIG_X86_DEBUG_FPU build failure
+
+When CONFIG_X86_DEBUG_FPU is defined the alternatives_patched symbol
+is pulled in as a dependency which results in a build failure.  To
+prevent this undefine CONFIG_X86_DEBUG_FPU to disable the WARN_ON_FPU()
+macro and rely on WARN_ON_ONCE debugging checks which were previously
+added.

+Subject: [PATCH] Allow FPU usage in user and kernel thread contexts
+
+Even for dedicated kernel threads we apparently cannot be
+guaranteed that the kernel won't modify the FPU state which
+we saved in the task struck.  Allocate our own per-cpu state
+to preserve the saved register state.  Aside from correctness,
+this allows use of the FPU in user threads again.

-Description: Solaris Porting Layer user-space utilities for Linux
- The Solaris Porting Layer (SPL) is a Linux kernel module which provides
- many of the Solaris kernel APIs. This shim layer makes it possible to
- run Solaris kernel code in the Linux kernel with relatively minimal
- modification. The Solaris Porting LAyer Tests (SPLAT) is a Linux kernel
- module which provides a testing harness for the SPL module.
- .
- SPL can be particularly useful when you want to track upstream Illumos
- (or any other OpenSolaris fork) development closely and don't want the
- overhead of maintaining a large patch which converts Solaris primitives
- to Linux primitives.
- .
- This package includes the user space utilities needed to test and debug
- the SPL and SPLAT kernel modules.

-Subject: [PATCH] increase-default-zcmd-allocation-to-256K
-
-Increase default zcmd allocation to 256K (LP: #567557)
-
-When creating hundreds of clones (for example using containers with
-LXD) cloning slows down as the number of clones increases over time.
-The reason for this is that the fetching of the clone information
-using a small zcmd buffer requires two ioctl calls, one to determine
-the size and a second to return the data. However, this requires
-gathering the data twice, once to determine the size and again to
-populate the zcmd buffer to return it to userspace.
-
-These are expensive ioctl() calls, so instead, make the default buffer
-size much larger: 256K. This may sound large, but on 64 bit systems
-running ZFS this is not a huge chunk of memory for the speed
-improvement we gains for large sets of clones:
-
-        16K zcmd        256K zcmd
-Clones	Time    Clones  Time    Clone   % improvement
-        (secs) 	per sec (secs)  per sec

-As one can see, with > 2000 clones we get 25-40% speed
-improvement.

-This patch was originally suggested by Brian Behlendorf
-(see https://github.com/zfsonlinux/zfs/issues/6372), however
-this fix is a more generic fix to cover all zcmd cases.

-Subject: [PATCH] Fix deadlock between zfs umount & snapentry_expire
-
-zfs umount -> zfsctl_destroy() takes the zfs_snapshot_lock as a
-writer and calls zfsctl_snapshot_unmount_cancel(), which waits
-for snapentry_expire() if present (when snap is automounted).
-This snapentry_expire() itself then waits for zfs_snapshot_lock
-as a reader, resulting in a deadlock.
-
-The fix is to only hold the zfs_snapshot_lock over the tree
-lookup and removal.  After a successful lookup the lock can
-be dropped and zfs_snapentry_t will remain valid until the
-reference taken by the lookup is released.

With submodules we still do not copy over a potential big .git folder, as we as submodule user have the submodules .git state in our .git/modules folder where the submodule just references to.

Before the SPL->ZFS merge the spl userspace package wrote the file (by parsing/ mangling the output of hostid (1)) Since ZFS provides the zgenhostid script, which creates a random 4 byte hostid and writes it to /etc/hostid, we use that instead. (hostid (1) default to mangling a configured ip of the system, which can be the same across multiple installs (install happens with the same ip) Signed-off-by: Stoiko Ivanov <s.ivanov@proxmox.com>	2019-05-24 11:44:34 +02:00
