[LU-15993] ofd_commitrw() can leak pages due to failed nodemap

• Type: Bug
• Resolution: Fixed
• Priority: Minor
• Fix Version/s: Lustre 2.16.0, Lustre 2.15.2
• Severity: 3
• Assignee: Alex Zhuravlev
• Reporter: Alex Zhuravlev

Description

	if (cmd == OBD_BRW_WRITE) {
		struct lu_nodemap *nodemap;
		__u32 mapped_uid, mapped_gid, mapped_projid;

		nodemap = nodemap_get_from_exp(exp);
		if (IS_ERR(nodemap))
			RETURN(PTR_ERR(nodemap));

thus ofd_commitrw_write() (so dt_bufs_put()) won't be called
