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
|
|
