| Subject: [PATCH] RDMA/qedr: Fix srqs xarray initialization |
| |
| commit 73ab512f720298aabe23b34110e3f6a8545b0ba5 upstream. |
| |
| There was a missing initialization for the srqs xarray. |
| SRQs xarray can also be called from irq context when searching |
| for an element and uses the xa_XXX_irq apis, therefore should |
| be initialized with IRQ flags. |
| |
| Fixes: 9fd15987ed27 ("qedr: Convert srqidr to XArray") |
