vfs: use kmalloc() to allocate fdmem if possible
Use kmalloc() to allocate fdmem if possible.
vmalloc() is used as a fallback solution for fdmem allocation. A new
helper function __free_fdtable() is introduced to reduce the lines of
code.
A potential bug, vfree() a memory allocated by kmalloc(), is fixed.
[akpm@linux-foundation.org: use __GFP_NOWARN, uninline alloc_fdmem() and free_fdmem()]
