Subject: [PATCH v2 0/5] fscache/cachefiles: Some bugfixes

Changes since V1[1]:
 - Removed some incorrect patches.
 - Modified the description of the first patch.
 - Modified the fourth patch to move fput out of lock execution.

Recently, I sent the first version of the patch series. After some
discussions, I made modifications to a few patches and have now officially
sent this second version.

This patchset mainly includes 5 fix patches about fscache/cachefiles.
Additionally, patches 2, 3, and 5 have already been ACKed. The first patch
fixes an issue with the incorrect return length, and the fourth patch
addresses a null pointer dereference issue with file.
