| 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. |
