[f2fs-dev] [PATCH v3 RESEND] f2fs: support F2FS_IOC_PRECACHE_EXTENTS

This patch introduces a new ioctl F2FS_IOC_PRECACHE_EXTENTS to precache extent info like ext4, in order to gain better performance during triggering AIO by eliminating synchronous waiting of mapping info. Referred commit: 7869a4a6c5ca ("ext4: add support for extent pre-caching") In addition,

[f2fs-dev] [PATCH] f2fs: avoid hungtask when gc encrypted block if io_bits is set

When io_bits is set, gc encrypted block may trigger the following hungtask. Since io_bits requires aligned block address, f2fs_submit_page_write may return -EAGAIN if new_blkaddr does not satisify io_bits alignment. So let's try to alloc new block address to make sure encrypted page could be

[f2fs-dev] [PATCH] f2fs: prevent newly created inode from being dirtied incorrectly

Now, we invoke f2fs_mark_inode_dirty_sync() to make an inode dirty in advance of creating a new node page for the inode. By this, some inodes whose node page is not created yet can be linked into the global dirty list. If the checkpoint is executed at this moment, the inode will be written back
