d6423b5527 romfs: expand file cache by CONFIG_FS_ROMFS_FCACHE_NSECTORS 
The default size of file cache is size of a sector, it may
not be good size for optimizing read/write speed in physical
device. So we can set the config according to speed test profile
to optimize access IO speed.

dd2ffbc768 Fixes for GPT partition parsing 
1. Don't handle invalid or empty pte entries

num_partition_entries field in GPT typically means number of maximum entries
and not the number of used entries. Empty entries are indentified with
"0" partition type guid. Loop through all the entries

2. Fix the GPT partition size calculation

"ending_lba" is included in the partition, it is not the start of the next one.
Thus the correct size of the partition is end-start+1

reason:
epoll_close -> close -> epoll_do_close (free inode)
                     -> inode_release  (reuse inode, crash)

fix:
use the global inode to match the fd which will return to user.
