gfs2: stop using generic_writepages in gfs2_ail1_start_one

2022-07-22T17:59:15+00:00

Use filemap_fdatawrite_wbc instead of generic_writepages in gfs2_ail1_start_one so that the functin can also cope with address_space operations that only implement ->writepages and to properly account for cgroup writeback.

fs/gfs2: Use the enum req_op and blk_opf_t types

2022-07-14T18:14:32+00:00

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.

gfs2: tiny cleanup in gfs2_log_reserve

2021-08-19T17:31:17+00:00

Function gfs2_log_reserve was setting revoke_blks to 0. There's no need because it calculates it shortly thereafter. This patch removes the unnecessary set. Signed-off-by: Bob Peterson

gfs2: Clean up revokes on normal withdraws

2021-05-20T11:31:37+00:00

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

gfs2: Fix a number of kernel-doc warnings

2021-04-09T20:14:13+00:00

Building the kernel with W=1 results in a number of kernel-doc warnings like incorrect function names and parameter descriptions. Fix those, mostly by adding missing parameter descriptions, removing left-over descriptions, and demoting some less important kernel-doc comments into regular comments. Originally proposed by Lee Jones; improved and combined into a single patch by Andreas. Signed-off-by: Lee Jones Signed-off-by: Andreas Gruenbacher

treewide: Change list_sort to use const pointers

2021-04-08T23:04:22+00:00

list_sort() internally casts the comparison function passed to it to a different type with constant struct list_head pointers, and uses this pointer to call the functions, which trips indirect call Control-Flow Integrity (CFI) checking. Instead of removing the consts, this change defines the list_cmp_func_t type and changes the comparison function types of all list_sort() callers to use const pointers, thus avoiding type mismatches.

gfs2: bypass log flush if the journal is not live

2021-03-12T14:52:48+00:00

Patch fe3e397668775 ("gfs2: Rework the log space allocation logic") changed gfs2_log_flush to reserve a set of journal blocks in case no transaction is active. However, gfs2_log_flush also gets called in cases where we don't have an active journal, for example, for spectator mounts. In that case, trying to reserve blocks would sleep forever, but we want gfs2_log_flush to be a no-op instead.
