Patch "Btrfs: send, fix file hole not being preserved due to inline extent" has been added to the 4.4-stable tree

For example, when the page size is 4Kb and compression is enabled: $ mkfs.btrfs -f /dev/sdb $ mount -o compress /dev/sdb /mnt $ xfs_io -f -c "pwrite -S 0xaa 0 4K" -c "fsync" /mnt/foobar $ xfs_io -c "pwrite -S 0xbb 8K 4K" -c "fsync" /mnt/foobar In this case we get a compressed inline extent, representing 4Kb of data, followed by a hole extent and then a regular data extent. The inline extent was not expanded/converted to a regular extent exactly because it represents 4Kb of data. This does not cause any apparent problem (such as the issue solved by commit e1699d2d7bf6 ("btrfs: add missing memset while reading compressed inline extents")) except trigger an unexpected case in the incremental send code path that makes us issue an operation to write a hole when it's not needed, resulting in more writes at the receiver and wasting space at the receiver. So teach the incremental send code to deal with this particular case. The issue can be currently triggered by running fstests btrfs/137 with compression enabled (MOUNT_OPTIONS="-o compress" ./check btrfs/137).

Enabling DFS/no infra flags in driver results in applying all DFS related restrictions (like doing CAC etc before this channel moves to 'available state') for these channels even though the country code is programmed as 'India' in he hardware, fix this by relaxing the frequency range while applying RADAR flags only if the country code is programmed to India. If the frequency range needs to modified based on different country code, ath_is_radar_freq can be extended/modified dynamically.

Patch "ARM: 8668/1: ftrace: Fix dynamic ftrace with DEBUG_RODATA and !FRAME_POINTER" has been added to the 4.4-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled ARM: 8668/1: ftrace: Fix dynamic ftrace with DEBUG_RODATA and !FRAME_POINTER to the 4.4-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: arm-8668-1-ftrace-fix-dynamic-ftrace-with-debug_rodata-and-frame_pointer.patch and it can be found in the queue-4.4 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From foo@baz Thu Mar 22 14:57:32 CET 2018 From: Abel Vesa <abelvesa(a)linux.com> Date: Mon, 3 Apr 2017 23:58:54 +0100 Subject: ARM: 8668/1: ftrace: Fix dynamic ftrace with DEBUG_RODATA and !FRAME_POINTER From: Abel Vesa <abelvesa(a)linux.com> [ Upstream commit 6f05d0761af612e04572ba4d65b4c0274a88444f ] The support for dynamic ftrace with CONFIG_DEBUG_RODATA involves overriding the weak arch_ftrace_update_code() with a variant which makes the kernel text writable around the patching. This override was however added under the CONFIG_OLD_MCOUNT ifdef, and CONFIG_OLD_MCOUNT is only enabled if frame pointers are enabled. This leads to non-functional dynamic ftrace (ftrace triggers a WARN_ON()) when CONFIG_DEBUG_RODATA is enabled and CONFIG_FRAME_POINTER is not. Move the override out of that ifdef and into the CONFIG_DYNAMIC_FTRACE ifdef where it belongs.
