zx_status_t GetLockedPage (pgoff_t index, LockedPage * out)It returns a locked Page corresponding to |index| from |page_tree_|.
If there is no Page, it creates and returns a locked Page.
Defined at line 327 of file ../../src/storage/f2fs/file_cache.cc
zx::result<std::vector<LockedPage>> GetLockedPages (pgoff_t start, pgoff_t end)It returns locked Pages corresponding to [start - end) from |page_tree_|.
Defined at line 298 of file ../../src/storage/f2fs/file_cache.cc
zx::result<std::vector<fbl::RefPtr<Page>>> GetPages (const pgoff_t start, const pgoff_t end)It does the same thing as the above methods except that it returns unlocked Pages.
Defined at line 309 of file ../../src/storage/f2fs/file_cache.cc
std::vector<LockedPage> FindLockedPages (pgoff_t start, pgoff_t end)It returns locked Pages corresponding to [start - end) from |page_tree_|.
If there is no corresponding Page, the returned page will be a null page.
Defined at line 304 of file ../../src/storage/f2fs/file_cache.cc
VnodeF2fs & GetVnode ()Defined at line 333 of file ../../src/storage/f2fs/file_cache.h
zx_status_t FindPage (pgoff_t index, fbl::RefPtr<Page> * out)It returns an unlocked Page corresponding to |index| from |page_tree|.
If it fails to find the Page in |page_tree_|, it returns ZX_ERR_NOT_FOUND.

VmoManager & GetVmoManager ()Defined at line 341 of file ../../src/storage/f2fs/file_cache.h
std::vector<LockedPage> InvalidatePages (pgoff_t start, pgoff_t end, bool zero)It invalidates Pages within the range of |start| to |end| in |page_tree_|. If |zero| is set,
the data of the corresponding pages are zeored. Then, it evicts all Pages within the range and
returns them locked.
Defined at line 435 of file ../../src/storage/f2fs/file_cache.cc
void Reset ()It invalidates all Pages from |page_tree_|.
Defined at line 467 of file ../../src/storage/f2fs/file_cache.cc
void ClearDirtyPages ()Clear all dirty pages.
Defined at line 453 of file ../../src/storage/f2fs/file_cache.cc
void Downgrade (Page * raw_page)Only Page::RecyclePage() is allowed to call it.
Defined at line 244 of file ../../src/storage/f2fs/file_cache.cc
size_t GetReadHint (pgoff_t start, size_t size, size_t max_size, bool high_memory_pressure)It returns a proper read size within the range of [size, size + max_size) according to the
status of recently used pages and memory pressure level.
Defined at line 472 of file ../../src/storage/f2fs/file_cache.cc
F2fs * fs ()Defined at line 254 of file ../../src/storage/f2fs/file_cache.cc
std::vector<fbl::RefPtr<Page>> FindDirtyPages (const WritebackOperation & operation)It returns a set of dirty Pages that meet |operation|.

void EvictCleanPages ()It evicts every clean, inactive page.
Defined at line 544 of file ../../src/storage/f2fs/file_cache.cc
void WaitOnWriteback (Page & page)It provides wait() and notify() for kPageWriteback flag of Page.
