Message-Id: <07010a2ad79559c412949f0005dbe3cb03d8416e.1498504812.git.ps@pks.im> From: Patrick Steinhardt <ps@pks.im> Date: Mon, 26 Jun 2017 21:20:45 +0200 Subject: [PATCH] 9pfs: include <linux/limits.h> for XATTR_SIZE_MAX The function `v9fs_xattrcreate` makes use of the define `XATTR_SIZE_MAX` to reject attempts of creating xattrs with an invalid size, which is defined in <linux/limits.h>. On glibc-based systems, this header is indirectly included via <limits.h>, <bits/posix1_lim.h>, <bitts/local_lim.h>, but on other platforms this is not guaranteed due to not being part of the POSIX standard. One examples are systems based on musl libc, which do not include the <linux/limits.h> indirectly, which leads to `XATTR_SIZE_MAX` being undefined. Fix this error by directly include <linux/limits.h>. As the 9P fs code is being Linux-based either way, we can simply do so without breaking other platforms. This enables building 9pfs on musl-based systems.
