CVS commit: src/sys/kern

["Taylor R Campbell" <riastradh%netbsd.org@localhost>]

Module Name:    src
Committed By:   riastradh

Modified Files:
        src/sys/kern: subr_thmap.c

Log Message:
thmap(9): Test alloc failure, not THMAP_GETPTR failure.

THMAP_GETPTR may return nonnull even though alloc returned zero.

Note that this failure branch is not actually appropriate;
thmap_create should not fail.  We really need to pass KM_SLEEP
through in this call site even though there are other call sites for
which KM_NOSLEEP is appropriate.
