Konstantin Belousov 695e0701a0 buffer pager: deref ucred immediately after read. ... Ucred is passed to bread(9) so that non-local filesystems use proper credentials. But, since clean buffer might be cached unless buf_pager_relbuf is not enabled, it makes credentials to have extra reference until buffer is reclaimed. Ucred reference would prevent jail from destroying if creds are jailed. Dereferencing the read credentials on the valid buffer avoid that, and should be fine because the buffer is valid and does not need re-read.
