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 367 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 338 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 349 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 344 of file ../../src/storage/f2fs/file_cache.cc
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.
Defined at line 377 of file ../../src/storage/f2fs/file_cache.cc
std::vector<LockedPage> InvalidatePages (pgoff_tstart,pgoff_tend,boolzero)
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 475 of file ../../src/storage/f2fs/file_cache.cc
void Reset ()It invalidates all Pages from |page_tree_|.
Defined at line 507 of file ../../src/storage/f2fs/file_cache.cc
void ClearDirtyPages ()Clear all dirty pages.
Defined at line 493 of file ../../src/storage/f2fs/file_cache.cc
size_t GetReadHint (pgoff_tstart,size_tsize,size_tmax_size,boolhigh_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 512 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|.
Defined at line 533 of file ../../src/storage/f2fs/file_cache.cc
void EvictCleanPages ()It evicts every clean, inactive page.
Defined at line 584 of file ../../src/storage/f2fs/file_cache.cc
void WaitOnWriteback (Page & page)It provides wait() and notify() for kPageWriteback flag of Page.
Defined at line 598 of file ../../src/storage/f2fs/file_cache.cc
