NAMEtruncate_pagecache − unmap and remove pagecache that has been truncated

---

SYNOPSISvoid truncate_pagecache(struct inode * inode, loff_t oldsize, loff_t newsize);

---

ARGUMENTSinode inode oldsize old file size newsize new file size

---

DESCRIPTIONinode´s new i_size must already be written before truncate_pagecache is called​. This function should typically be called before the filesystem releases resources associated with the freed range (eg​. deallocates blocks)​. This way, pagecache will always stay logically coherent with on−disk format, and the filesystem would not have to deal with situations such as writepage being called for a page that has already had its underlying blocks deallocated​.
