This fixes CAP_SYS_RESOURCE denial of selinux when using resgid, since it seems selinux reports it at the first place, but mostly we don't need to check this condition first. Reviewed-by:

This patch supports to recognize hot file extension in f2fs, so that we can allocate proper hot segment location for its data, which can lead to better hot/cold seperation in filesystem. In addition, we changes a bit on query/add/del operation method for extension_list sysfs entry as below: - Query: cat /sys/fs/f2fs/<disk>/extension_list - Add: echo 'extension' > /sys/fs/f2fs/<disk>/extension_list - Del: echo '!extension' > /sys/fs/f2fs/<disk>/extension_list - Add: echo '[h/c]extension' > /sys/fs/f2fs/<disk>/extension_list - Del: echo '[h/c]!extension' > /sys/fs/f2fs/<disk>/extension_list - [h] means add/del hot file extension - [c] means add/del cold file extension Signed-off-by:

This patch adds an mount option, "alloc_mode=%s" having two options, "default" and "reuse". In "alloc_mode=reuse" case, f2fs starts to allocate segments from 0'th segment all the time to reassign segments. It'd be useful for small-sized eMMC parts. Reviewed-by:

Previously, we will store all nat version bitmap in checkpoint pack block, so our total node entry number has a limitation which caused total node number can not exceed (3900 * 8) block * 455 node/block = 14196000. So that once user wants to create more nodes in large size image, it becomes a bottleneck, that's unreasonable. This patch detects the new layout of nat/sit version bitmap in image in order to enable supporting large nat bitmap. Signed-off-by:

Previous dentry page uses highmem, which will cause panic in platforms using highmem (such as arm), since the address space of dentry pages from highmem directly goes into the decryption path via the function fscrypt_fname_disk_to_usr. But sg_init_one assumes the address is not from highmem, and then cause panic since it doesn't call kmap_high but kunmap_high is triggered at the end. To fix this problem in a simple way, this patch avoids to put dentry page in pagecache into highmem. Signed-off-by:

This patch splits need_inplace_update to two functions: a. should_update_inplace() includes all conditions that we must use IPU. b. should_update_outplace() includes all conditions that we must use OPU. So that, in f2fs_ioc_set_pin_file() and f2fs_defragment_range(), we can use corresponding function to check whether we can trigger OPU/IPU or not. Signed-off-by:

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 by writeback_single_inode() and finally update_inode_page() will fail to detach the inode from the global dirty list because the inode doesn't have a node page. The problem is that the inode's state in VFS layer will become clean after execution of writeback_single_inode() and it's still linked in the global dirty list of f2fs and this will cause a kernel panic. So, we will prevent the newly created inode from being dirtied during the FI_NEW_INODE flag of the inode is set. We will make it dirty right after the flag is cleared. Signed-off-by:

Cgroup writeback requires explicit support from the filesystem. f2fs's data and node writeback IOs go through __write_data_page, which sets fio for submiting IOs. So, we add io_wbc for fio, associate bios with blkcg by invoking wbc_init_bio() and account IOs issuing by wbc_account_io(). In addtion, f2fs_fill_super() is updated to set SB_I_CGROUPWB. Meta writeback IOs is left alone by this patch and will always be attributed to the root cgroup. The results show that f2fs can throttle writeback nicely for data writing and file creating.

This is a pure automated search-and-replace of the internal kernel superblock flags. The s_flags are now called SB_*, with the names and the values for the moment mirroring the MS_* flags that they're equivalent to. Note how the MS_xyz flags are the ones passed to the mount system call, while the SB_xyz flags are what we then use in sb->s_flags. The script to do this was: # places to look in; re security/*: it generally should *not* be # touched (that stuff parses mount(2) arguments directly), but # there are two places where we really deal with superblock flags.
