Bug Description
SRU Justification
Impact: Shiftfs does not mark it's slab cache as reclaimable. While this is not a big deal it is not nice to the kernel in general. The shiftfs cache is not so important that it can't be reclaimed.
Regression Potential: Limited to shiftfs. This patch has been tested for multiple days and has not caused any regressions.
Test Case:
Open a lot of files in shiftfs to get them into the cache and then cause memory pressure via e.g. stress-ng and see if the shiftfs cache shrinks.
Target Kernels: All LTS kernels with shiftfs support.
