pNFS: Fix the pnfs block driver's calculation of layoutget size

2024-01-25T23:44:44Z

[ Upstream commit 8a6291bf3b0eae1bf26621e6419a91682f2d6227 ] Instead of relying on the value of the 'bytes_left' field, we should calculate the layout size based on the offset of the request that is being written out.

blocklayoutdriver: Fix reference leak of pnfs_device_node

2024-01-25T23:44:44Z

[ Upstream commit 1530827b90025cdf80c9b0d07a166d045a0a7b81 ] The error path for blocklayout's device lookup is missing a reference drop for the case where a lookup finds the device, but the device is marked with NFS_DEVICEID_UNAVAILABLE.

fs/nfs: Use enum req_op where appropriate

2022-07-14T18:14:33Z

Improve static type checking by using enum req_op for request operations. Rename an 'rw' argument into 'op' since that name is typically used for request operations. This patch does not change any functionality. Note: REQ_OP_READ = READ = 0 and REQ_OP_WRITE = WRITE = 1.

block: pass a block_device and opf to bio_alloc

2022-02-02T14:49:59Z

Pass the block_device and operation that we plan to use this bio for to bio_alloc to optimize the assignment. NULL/0 can be passed, both for the passthrough case on a raw request_queue and to temporarily avoid refactoring some nasty code. Also move the gfp_mask argument after the nr_vecs argument for a much more logical calling convention matching what most of the kernel does.

bio_alloc will never fail when it can sleep. Remove the now simple bl_alloc_init_bio helper and open code it in the only caller. Signed-off-by: Christoph Hellwig Link: https://lore.kernel.org/r/20220124091107.642561-4-hch@lst.de Signed-off-by: Jens Axboe

block: Add bio_max_segs

2021-02-26T22:49:51Z

It's often inconvenient to use BIO_MAX_PAGES due to min() requiring the sign to be the same. Introduce bio_max_segs() and change BIO_MAX_PAGES to be unsigned to make it easier for the users. Reviewed-by: Chaitanya Kulkarni Signed-off-by: Matthew Wilcox (Oracle) Signed-off-by: Jens Axboe
