Håkon Bugge c62000bf27 rds: ib: Increment i_fastreg_wrs before bailing out ... commit 4351ca3fcb3ffecf12631b4996bf085a2dad0db6 upstream. We need to increment i_fastreg_wrs before we bail out from rds_ib_post_reg_frmr(). We have a fixed budget of how many FRWR operations that can be outstanding using the dedicated QP used for memory registrations and de-registrations. This budget is enforced by the atomic_t i_fastreg_wrs. If we bail out early in rds_ib_post_reg_frmr(), we will "leak" the possibility of posting an FRWR operation, and if that accumulates, no FRWR operation can be carried out. Fixes: 1659185fb4 ("RDS: IB: Support Fastreg MR (FRMR) memory registration mode") Fixes: 3a2886cca7 ("net/rds: Keep track of and wait for FRWR segments in use upon shutdown") Cc: stable@vger.kernel.org Signed-off-by: Håkon Bugge <haakon.bugge@oracle.com> Reviewed-by: Allison Henderson <allison.henderson@oracle.com> Link: https://patch.msgid.link/20250911133336.451212-1-haakon.bugge@oracle.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2025-09-25 11:16:50 +02:00
