Gao Xiang 24331050a3 erofs: fix small compressed files inlining ... Prior to ztailpacking feature, it's enough that each lcluster has two pclusters at most, and the last pcluster should be turned into an uncompressed pcluster when necessary. For example, _________________________________________________ |_ pcluster n-2 _|_ pcluster n-1 _|____ EOFed ____| which should be converted into: _________________________________________________ |_ pcluster n-2 _|_ pcluster n-1 (uncompressed)' _| That is fine since either pcluster n-1 or (uncompressed)' takes one physical block. However, after ztailpacking was supported, the game is changed since the last pcluster can be inlined now. And such case above is quite common for inlining small files. Therefore, in order to inline more effectively, special EOF lclusters are now supported which can have three parts at most, as illustrated below: _________________________________________________ |_ pcluster n-2 _|_ pcluster n-1 _|____ EOFed ____| ^ i_size Actually similar code exists in Yue Hu's original patchset [1], but I removed this part on purpose. After evaluating more real cases with small files, I've changed my mind.
