doc: correcting the debug path for cachefiles

2024-10-24T11:50:27+00:00

The original debug path is under "/sys/modules", that's wrong. The real path in kernel is "/sys/module". So we can correct it. Signed-off-by: Hongbo Li Link: https://lore.kernel.org/r/20241022013812.2880883-1-lihongbo22@huawei.com Signed-off-by: Christian Brauner

netfs: clean up after renaming FSCACHE_DEBUG config

2024-08-12T20:03:26+00:00

Commit 6b8e61472529 ("netfs: Rename CONFIG_FSCACHE_DEBUG to CONFIG_NETFS_DEBUG") renames the config, but introduces two issues: First, NETFS_DEBUG mistakenly depends on the non-existing config NETFS, whereas the actual intended config is called NETFS_SUPPORT. Second, the config renaming misses to adjust the documentation of the functionality of this config. Clean up those two points.

2022-04-08T22:54:37+00:00

The cookie is not used at all, remove it and update the usage in io.c and afs/write.c (which is the only user outside of fscache currently) at the same time.

docs: filesystems: caching/backend-api.rst: fix an object withdrawn API

2022-04-08T22:54:37+00:00

There's no fscache_are_objects_withdrawn() helper at all to test if cookie withdrawal is completed currently. The cache backend is using fscache_wait_for_objects() to wait all objects to be withdrawn.

docs: filesystems: caching/backend-api.rst: correct two relinquish APIs use

2022-04-08T22:54:37+00:00

1. cache backend is using fscache_relinquish_cache() rather than fscache_relinquish_cookie() to reset the cache cookie. 2. No fscache_cache_relinquish() helper currently, it should be fscache_relinquish_cache().
