Hi everyone,
The patch in this version has made the following changes compared to
the previous versionv(patch v4):
- adjusted the code style;
- introduced erofs_pcshr_{read,readahead}_{begin,end}() to switch
between anonymous inodes and real inodes;
- cleanup work for erofs_pcshr_fadvise();
- adjusted some variable names, etc.
The experiments were repeated, and the results were almost consistent.
