e4652bd3dc Squashed commit of the following: 
fs: Add truncate() support for userfs
    fs/unionfs:  Add truncate() support to the unionfs
    fs/tmpfs:  Add ftruncate() support to tmpfs
    syscall/: Add system call support for ftruncate()
    net/route:  Adding ftruncate() support eliminates an issue in file-based routing table management.
    fs:  Add basic framework to support truncate() and ftruncate().  The infrastructure is complete.  Now, however, the actual implementation of ftruncate() will have to be done for each file system.

a6aa4ac5f5 fs/procfs: Optimization of previous commits. /proc/umm and proc/progmem are deleted. /proc/kmm is renamed /proc/meminfo and contains the output that was in all three files previously. 2017-11-13 13:33:12 -06:00

f3b37e5da3 fs/procfs/fs_procfsprogrem: Add /proc/progmem. This is an alternative way to get the information that was previoulsy available in apps/system/free. apps/system/free was removed beause it made illegal calls into the OS violating the portable interface. This new procfs entry provides the same information with no such violation. 2017-11-13 09:08:39 -06:00

07f441eecb Missing some conditional logic for cases where mountpoint procfd entries excluded. 2017-10-27 06:06:20 -06:00

ea13e24392 Correct a problem that was causing an apparent directory to be reported as a file instead of a directory by opendir. 
This happened after adding these three new procfs entries:

  fs/block
  fs/mount
  fs/usage

Of course, there is no directory fs in this case, only three files that have fs/ in their relative pathnames.  The logic was detecting that fs was the name of the enty to report, but it was then declaring that fs was a file (because fs/block is of type file).

This was fixed by adding a check for matching lenghts.  i.e., if strlen(fs) != strlen(fs/block), then report fs as a directory instead of a file.

1ed816de4b Squashed commit of the following: 
fs/mount:  Implements procfs /proc/fs/blocks and /proc/fs/usage files, replacing the NSH df command.
    fs/mount:  Implements procfs /proc/fs/mount file, replacing the NSH mount command when there are not arguments.
    fs/: Move prototype of foreach_mountpoint out of include/nuttx/fs/fs.h to fs/mount/mount.h.  Add framework for the mount procfs (initial commit is just a close of the net/route table procfs.
