2016-07-12perf symbols: Provide a GElf_Nhdr typedefArnaldo Carvalho de Melo
This one can be safely defined to be Elf64_Nhdr, as it is in elfutils's libelf, but not on musl libc, as both Elf64_Nhdr and Elf32_Nhdr have the same layout.

2016-07-12tools: Introduce str_error_r()Arnaldo Carvalho de Melo
The tools so far have been using the strerror_r() GNU variant, that returns a string, be it the buffer passed or something else. But that, besides being tricky in cases where we expect that the function using strerror_r() returns the error formatted in a provided buffer (we have to check if it returned something else and copy that instead), breaks the build on systems not using glibc, like Alpine Linux, where musl libc is used. So, introduce yet another wrapper, str_error_r(), that has the GNU interface, but uses the portable XSI variant of strerror_r(), so that users rest asured that the provided buffer is used and it is what is returned.

2016-07-12tools: hv: Add a script to help bonding synthetic and VF NICsHaiyang Zhang
This script helps to create bonding network devices based on synthetic NIC (the virtual network adapter usually provided by Hyper-V) and the matching VF NIC (SRIOV virtual function). So the synthetic NIC and VF NIC can function as one network device, and fail over to the synthetic NIC if VF is down. Mayjor distros (RHEL, Ubuntu, SLES) supported by Hyper-V are supported by this script. Signed-off-by: Haiyang Zhang <haiyangz@microsoft.com> Reviewed-by: K. Y.

2016-07-12GFS2: Check rs_free with rd_rsspin protectionBob Peterson
For the last process to close a file opened for write, function gfs2_rsqa_delete was deleting the file's inode's block reservation out of the rgrp reservations tree. Then it was checking to make sure rs_free was 0, but it was performing the check outside the protection of rd_rsspin spin_lock. The rd_rsspin spin_lock protection is needed to prevent a race between the process freeing the reservation and another who is allocating a new set of blocks inside the same rgrp for the same inode, thus changing its value.
