Subject: [PATCH 0/8] netfs/cachefiles: Some bugfixes
Hi!
We recently discovered some bugs through self-discovery and testing in
erofs ondemand loading mode, and this patchset is mainly used to fix
them. These patches are relatively simple changes, and I would be excited
to discuss them together with everyone. Below is a brief introduction to
each patch:
Patch 1: Fix for wrong block_number calculated in ondemand write.
Patch 2: Fix for wrong length return value in ondemand write.
Patch 3: Fix missing position update in ondemand write, for scenarios
involving read-ahead, invoking the write syscall.
Patch 4: Previously, the last redundant data was cleared during the umount
phase. This patch remove unnecessary data in advance.
Patch 5: Code clean up for cachefiles_commit_tmpfile().
Patch 6: Modify error return value in cachefiles_daemon_secctx().
Patch 7: Fix object->file Null-pointer-dereference problem.
Patch 8: Fix for memory out of order in fscache_create_volume().
