ee8abb8160 FS: Don't build block driver proxy if PSEUDOFS_OPERATIONS are disabled. 2017-03-04 08:25:20 -06:00

0a192361de Revert "FS: Fix backward conditional logic that prevent unlink() from building in some configurations."
Oops.  It was not backward.  Enable == !Disable.  Negative logic is confusing.

This reverts commit 1fcf353e89.

8f2c7198ed inode_find: Now takes struct inode_desc_s type as input. This was necessary before that structure includes some data storage. It was used within inode_find(), but that means that the life of the data was the life of inode_find(). That data must persist longer. It is now provided by the caller so that the life of the data persists for the entire life of the caller. 2017-02-05 09:51:42 -06:00

3f731241cb fs/inode/, fs/vfs/, and sched/task/: File and socket descriptors are no longer allocated for kernel threads.

e31d5125ae Add support for a variadic ioctl() function. The ioctl() interface is a non-standard, Unix interface. NuttX has always used the older, three-parameter version. Most contemporary systems now, however, use a variadic form of the ioctl() function. Added an option to insert a shim layer to adapt the three-parameter ioctl() to use the variadic interface form. Internally, the ioctl handling is the same three-parameter logic. The only real complexity to the shim is in how the system calls must be handled. 2014-11-29 10:53:22 -06:00
