Commit Message

Daniel Henrique Barboza March 27, 2024, 9:31 a.m. UTC 
We've consolidated all local 9p tests but the hardlink ones. To make
fs_unlinkat_hardlink() to act exactly like fs_hardlink_file() we added
the g_assert(st_link...) checks in fs_unlinkat_hardlink() as well.

After that:

- remove fs_hardlink_file(). Rename fs_unlinkat_hardlink() to
  fs_create_unlinkat_hardlink();

- remove the created dir and 'real_file' at the end of
  fs_create_unlinkat_hardlink().

After this patch all local 9p tests are now cleaning themselves up after
execution and we shouldn't experience errors like the one reported in
[1].
