1 A laundry list of things that need looking at, most of which will
2 require more work than the average checkpatch cleanup...
4 Note that some of these entries may not be bugs - they're things
5 that need to be looked at, and *possibly* fixed.
7 Clean up the ffsCamelCase function names.
9 Fix (thing)->flags to not use magic numbers - multiple offenders
11 Sort out all the s32/u32/u8 nonsense - most of these should be plain int.
13 exfat_core.c - ffsReadFile - the goto err_out seem to leak a brelse().
14 same for ffsWriteFile.
16 All the calls to fs_sync() need to be looked at, particularly in the
17 context of EXFAT_DELAYED_SYNC. Currently, if that's defined, we only
18 flush to disk when sync() gets called. We should be doing at least
19 metadata flushes at appropriate times.
21 ffsTruncateFile - if (old_size <= new_size) {
22 That doesn't look right. How did it ever work? Are they relying on lazy
23 block allocation when actual writes happen? If nothing else, it never
24 does the 'fid->size = new_size' and do the inode update....
26 ffsSetAttr() is just dangling in the breeze, not wired up at all...
28 Convert global mutexes to a per-superblock mutex.
30 Right now, we load exactly one UTF-8 table. Check to see
31 if that plays nice with different codepage and iocharset values
32 for simultanous mounts of different devices
34 exfat_rmdir() checks for -EBUSY but ffsRemoveDir() doesn't return it.
35 In fact, there's a complete lack of -EBUSY testing anywhere.
37 There's probably a few missing checks for -EEXIST
39 check return codes of sync_dirty_buffer()
41 Why is remove_file doing a num_entries++??
43 Double check a lot of can't-happen parameter checks (for null pointers for
44 things that have only one call site and can't pass a null, etc).
46 All the DEBUG stuff can probably be tossed, including the ioctl(). Either
47 that, or convert to a proper fault-injection system.
49 exfat_remount does exactly one thing. Fix to actually deal with remount
50 options, particularly handling R/O correctly. For that matter, allow
51 R/O mounts in the first place.
53 Figure out why the VFAT code used multi_sector_(read|write) but the
54 exfat code doesn't use it. The difference matters on SSDs with wear leveling.
56 exfat_fat_sync(), exfat_buf_sync(), and sync_alloc_bitmap()
57 aren't called anyplace....
59 Create helper function for exfat_set_entry_time() and exfat_set_entry_type()
60 because it's sort of ugly to be calling the same functionn directly and
61 other code calling through the fs_func struc ponters...
63 clean up the remaining vol_type checks, which are of two types:
64 some are ?: operators with magic numbers, and the rest are places
65 where we're doing stuff with '.' and '..'.
