+Subject: [PATCH] zfs-test/mmap_seek: fix build on musl
+
+it needs linux/fs.h for SEEK_DATA and friends
+
+without linux/fs.h:
+
+```
+mmap_seek.c
+mmap_seek.c: In function 'seek_data':
+mmap_seek.c:37:40: error: 'SEEK_DATA' undeclared (first use in this function);
+did you mean 'SEEK_SET'?
+   37 |  off_t data_offset = lseek(fd, offset, SEEK_DATA);
+```
+
+also it needs sys/sysmacros.h for P2ROUNDUP
+without it:
+
+```
+mmap_seek.c: In function 'main':
+mmap_seek.c:122:19: warning:
+implicit declaration of function 'P2ROUNDUP' [-Wimplicit-function-declaration]
+  122 |  seek_hole(fd, 0, P2ROUNDUP(file_size / 2, block_size));
+      |                   ^~~~~~~~~
