+Subject: [PATCH] block/export/fuse.c: fix fuse-lseek on uclibc or musl
+
+Include linux/fs.h to avoid the following build failure on uclibc or
+musl raised since version 6.0.0:
+
+../block/export/fuse.c: In function 'fuse_lseek':
+../block/export/fuse.c:641:19: error: 'SEEK_HOLE' undeclared (first use in this function)
+  641 |     if (whence != SEEK_HOLE && whence != SEEK_DATA) {
+      |                   ^~~~~~~~~
+../block/export/fuse.c:641:19: note: each undeclared identifier is reported only once for each function it appears in
+../block/export/fuse.c:641:42: error: 'SEEK_DATA' undeclared (first use in this function); did you mean 'SEEK_SET'?
+  641 |     if (whence != SEEK_HOLE && whence != SEEK_DATA) {
+      |                                          ^~~~~~~~~
+      |                                          SEEK_SET
