and now add an independent pipe type

ea52220509 fs/shmfs: fix inode leak issue
If the shm file is removed and a subsequent close, only release shm
object, but inode is leaked. Should decrease refcount to release inode
when unmapped, that matched with refcount increase when mapped.

Another fix that remove the shm file failed.
nsh> rm /var/shm/pts_mmap_1_2_5
nsh: rm: unlink failed: 6

a4d6af8343 Check return from nxsem_wait_initialize()
Resolution of Issue 619 will require multiple steps, this part of the first step in that resolution:  Every call to nxsem_wait_uninterruptible() must handle the return value from nxsem_wait_uninterruptible properly.  This commit is only for those files under fs/inode.  Utility functions under fs/incode were modified so the changes do extend to other fs/ sub-directories as well.

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

62e588a0a4 VFS: Add an unlink method to the character driver interface. This is important because if the character driver inode is unlinked and there are no open references to the driver, then the driver resources will be stranded. On the unlink call, the driver has the opportunity (1) check if there an any open references, and (2) if not free the driver resources 2015-01-31 11:31:34 -06:00
