Description Christof Schmitt 2018-01-12 18:21:13 UTC
GPFS supports denying the DELETE sharemode. Using this results in the
problem that close_remove_share_mode() first tries to unlink() the
file and only after that requests to remove the sharemode. The unlink()
fails in this case when the file system denies the DELETE sharemode and
the file still exists after the "delete on close".

Patch for Samba 4.8

Backport to Samba 4.8. As vfs_gpfs only implements the
DELETE sharemode in 4.8 and newer and no other vfs module
implements the DELETE sharemode, a backport to 4.8
should be sufficient.
