dongjiuzhu1 09a9611ae9 fs/inode: using rwsem lock as inode_lock to avoid deadlock
Example:
When executing "df -h" on Core A to view mount information, this
process will traverse inode nodes, thereby holding the inode_lock.
Since the inode type of the mount point may be rpmsgfs, it will fetch statfs
information from another Core B.

Meanwhile, rcS on Core B needs to obtain file information from Core A,
which will be achieved by fetching stat information through rpmsgfs.
When this message arrives at Core A, a deadlock can occur between Core A's
rptun ap and nsh task.

However, both of these places involve read operations only, thus a reader-writer lock
can be utilized to prevent such a deadlock.

chenrun1 96206cbf9d fs/xxfs:Replace kmm with fs heap
Summary:
  1.Add configuration to allocate memory from the specified section
  2.Replace all memory operations (kmm_) in the vfs with
    fs_heap_. When FS_HEAPSIZE > 0, memory is requested for the file system by specifying a configured heap location. By default (i.e. FS_HEAPSIZE=0) fs_heap_ is equivalent to kmm_

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.

dongjiuzhu1 18819b6b24 sched/task: close file descriptor with O_CLOEXEC before active task or exec
VELAPLATFO-18473

refs:
https://man7.org/linux/man-pages/man2/fcntl.2.html
If the FD_CLOEXEC bit is set, the file descriptor will automatically
be closed during a successful execve(2).
(If the execve(2) fails, the file descriptor is left open.)

modify:
1. Ensure that the child task copies all fds of the parent task,
   including those with O_CLOEXE.
2. Make sure spawn_file_action is executed under fd with O_CLOEXEC,
   otherwise it will fail.
3. When a new task is activated or exec is called, close all fds
   with O_CLOEXEC flags.
