Subject: [PATCH] photosyst.c: fix build on musl
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Build on musl is broken since version 2.6.0 and
https://github.com/Atoptool/atop/commit/e889c66fbe1d0b7ae38fbcbaa46cea749257f486
because limits.h is not included:

photosyst.c: In function ‘lvmmapname’:
photosyst.c:1624:14: error: ‘PATH_MAX’ undeclared (first use in this function); did you mean ‘AF_MAX’?
   char  path[PATH_MAX];
              ^~~~~~~~
              AF_MAX
