gfs2: Use memcpy_{from,to}_page where appropriate

2023-07-03T20:30:48Z

Replace kmap_local_page() + memcpy() + kunmap_local() sequences with memcpy_{from,to}_page() where we are not doing anything else with the mapped page. Signed-off-by: Andreas Gruenbacher

gfs2: Convert remaining kmap_atomic calls to kmap_local_page

2023-07-03T20:30:47Z

Replace the remaining instances of kmap_atomic() ... kunmap_atomic() with kmap_local_page() ... kunmap_local(). In gfs2_write_buf_to_page(), we can call flush_dcache_page() after unmapping the page. Signed-off-by: Andreas Gruenbacher

gfs2: Convert gfs2_jhead_process_page() to use a folio

2022-08-02T16:34:03Z

Use folio_put_refs() to perform only one atomic operation instead of two. The other changes are straightforward conversions from page APIs to their folio equivalents. Signed-off-by: Matthew Wilcox (Oracle)

fs/gfs2: Use the enum req_op and blk_opf_t types

2022-07-14T18:14:32Z

Improve static type checking by using the enum req_op type for variables that represent a request operation and the new blk_opf_t type for variables that represent request flags. Combine the first two gfs2_submit_bhs() arguments into a single argument.

block: remove the per-bio/request write hint

With the NVMe support for this gone, there are no consumers of these hints left, so remove them. Signed-off-by: Christoph Hellwig Link: https://lore.kernel.org/r/20220304175556.407719-2-hch@lst.de Signed-off-by: Jens Axboe

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.

gfs2: be more verbose replaying invalid rgrp blocks

2021-08-19T17:31:17Z

This patch adds some crucial information when journal replay detects a replay of an obsolete rgrp block. For example, it wasn't printing the journal id or the generation number played. This just supplements what is logged in this unusual case. The function that actually complains about the replaying of an obsolete rgrp block has been split off to avoid long lines and sparse warnings. Signed-off-by: Bob Peterson

gfs2: Clean up revokes on normal withdraws

2021-05-20T11:31:37Z

Before this patch, the system ail lists were cleaned up if the logd process withdrew, but on other withdraws, they were not cleaned up. This included the cleaning up of the revokes as well. This patch reorganizes things a bit so that all withdraws (not just logd) clean up the ail lists, including any pending revokes. Signed-off-by: Bob Peterson Signed-off-by: Andreas Gruenbacher
