chenrun1 4cec713dbf fs_inode:Change the type of i_crefs to atomic_int
Summary:
  1.Modified the i_crefs from int16_t to atomic_int
  2.Modified the i_crefs add, delete, read, and initialize interfaces to atomic operations
The purpose of this change is to avoid deadlock in cross-core scenarios, where A Core blocks B Core’s request for a write operation to A Core when A Core requests a read operation to B Core.

Gregory Nutt 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.

Gregory Nutt 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
