The patch titled Subject: coda: fix reference counting in coda_file_mmap error path has been removed from the -mm tree. Its filename was coda-fix-reference-counting-in-coda_file_mmap-error-path.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Christian König <christian.koenig@amd.com> Subject: coda: fix reference counting in coda_file_mmap error path mmap_region() now calls fput() on the vma->vm_file. So we need to drop the extra reference on the coda file instead of the host file.
