2021-08-27fs/ntfs3: Restyle comment block in ni_parse_reparse()Kari Argillander1-6/+10
First of this fix one none utf8 char in this comment block. Maybe this happened because error in filesystem ;) Also this block was hard to read because long lines so make it max 80 long. And while we doing this stuff make little better grammer.

2021-08-27fs/ntfs3: Fix integer overflow in multiplicationColin Ian King1-1/+1
The multiplication of the u32 data_size with a int is being performed using 32 bit arithmetic however the results is being assigned to the variable nbits that is a size_t (64 bit) value. Fix a potential integer overflow by casting the u32 value to a size_t before the multiply to use a size_t sized bit multiply operation.
