2021-09-13fs/ntfs3: Limit binary search table sizeKari Argillander1-69/+41
Current binary search allocates memory for table and fill whole table before we start actual binary search. This is quite inefficient because table fill will always be O(n). Also if table is huge we need to reallocate memory which is costly. This implementation use just stack memory and always when table is full we will check if last element is <= and if not start table fill again. The idea was that it would be same cost as table reallocation.

2021-09-13fs/ntfs3: Add missing headers and forward declarations to ntfs_fs.hKari Argillander1-0/+31
We do not have headers at all in this file. We should have them so that not every .c file needs to include all of the stuff which this file need for building. This way we can remove some headers from other files and get better picture what is needed. This can save some compilation time. And this can help if we sometimes want to separate this one big header. Also use forward declarations for structs and enums when it not included straight with include and it is used in function declarations input. This will prevent possible compiler warning: xxx declared inside parameter list will not be visible outside of this definition or declaration Here is list which I made when parsing this. There is not necessarily all example from this header file, but this just proofs we need it. <linux/blkdev.h> SECTOR_SHIFT <linux/buffer_head.h> sb_bread(), put_bh <linux/cleancache.h> put_page() <linux/fs.h> struct inode (Just struct ntfs_inode need it) <linux/highmem.h> kunmap(), kmap() <linux/kernel.h> cpu_to_leXX() ALIGN <linux/mm.h> kvfree() <linux/mutex.h> struct mutex, mutex_(un/try)lock() <linux/page-flags.h> PageError() <linux/pagemap.h> read_mapping_page() <linux/rbtree.h> struct rb_root <linux/rwsem.h> struct rw_semaphore <linux/slab.h> krfree(), kzalloc() <linux/string.h> memset() <linux/time64.h> struct timespec64 <linux/types.h> uXX, __leXX <linux/uidgid.h> kuid_t, kgid_t <asm/div64.h> do_div() <asm/page.h> PAGE_SIZE "debug.h" ntfs_err() (Just one entry.

Show options should show option according documentation when some value is not default or when ever coder wants. Uid/gid are problematic because it is hard to know which are defaults. In file system there is many different implementation for this problem. Some file systems show uid/gid when they are different than root, some when user has set them and some show them always. There is also problem that what if root uid/gid change. This code just choose to show them always. This way we do not need to think this any more.

Remove unnecesarry remount flag handling. This does not do anything for this driver. We have already set SB_NODIRATIME when we fill super. Also noatime should be set from mount option. Now for some reson we try to set it when remounting. Lazytime part looks like it is copied from f2fs and there is own mount parameter for it. That is why they use it.
