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.

nfs/blocklayout: remove bl_alloc_init_bio

2022-02-02T14:49:59Z

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

treewide: Use fallthrough pseudo-keyword

2020-08-23T22:36:59Z

Replace the existing /* fall through */ comments and its variants with the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary fall-through markings when it is the case.

NFS/NFSD/SUNRPC: replace generic creds with 'struct cred'.

2018-12-19T18:52:46Z

SUNRPC has two sorts of credentials, both of which appear as "struct rpc_cred". There are "generic credentials" which are supplied by clients such as NFS and passed in 'struct rpc_message' to indicate which user should be used to authorize the request, and there are low-level credentials such as AUTH_NULL, AUTH_UNIX, AUTH_GSS which describe the credential to be sent over the wires. This patch replaces all the generic credentials by 'struct cred' pointers - the credential structure used throughout Linux. For machine credentials, there is a special 'struct cred *' pointer which is statically allocated and recognized where needed as having a special meaning. A look-up of a low-level cred will map this to a machine credential. Signed-off-by: NeilBrown Acked-by: J. Bruce Fields Signed-off-by: Anna Schumaker

page cache: Convert hole search to XArray

2018-10-21T14:46:33Z

The page cache offers the ability to search for a miss in the previous or next N locations. Rather than teach the XArray about the page cache's definition of a miss, use xas_prev() and xas_next() to search the page array. This should be more efficient as it does not have to start the lookup from the top for each index. Signed-off-by: Matthew Wilcox
