Message:

fix a bug in the mfs_write() and mfs_read_map() functions.

• mfs_read_map(): the inode size must be rounded up to the block size before testing

if "pos" is beyond the end of file.

• mfs_write(): fix inode size calculation and set BLOCK_FLAGS_NOREAD when a new block is allocated.

File:

• uspace/srv/fs/mfs/mfs_rw.c (modified) (2 diffs)

uspace/srv/fs/mfs/mfs_rw.c
