nilfs_copy_back_pages – copy back pages to original cache from shadow cache : destination page cache : source page cache
No pages must no be added to the cache during this process. This must be ensured by the caller.
Definition at line 311 of file page.c.
nilfs_copy_buffer – copy buffer data and flags : destination buffer : source buffer
Definition at line 115 of file page.c.
nilfs_find_uncommitted_extent - find extent of uncommitted data : inode : start block offset (in) : start offset of the found extent (out)
This function searches an extent of buffers marked "delayed" which starts from a block offset equal to or larger than . If such an extent was found, this will store the start offset in and return its length in blocks. Otherwise, zero is returned.
