| Subject: xfs: fix allocbt cursor leak in xfs_alloc_ag_vextent_near |
| |
| commit 76d095388b040229ea1aad7dea45be0cfa20f589 upstream. |
| |
| When we fail to find an matching extent near the requested extent |
| specification during a left-right distance search in |
| xfs_alloc_ag_vextent_near, we fail to free the original cursor that |
| we used to look up the XFS_BTNUM_CNT tree and hence leak it. |
