Subject: a bug in ramfs_nommu_resize function, passing old size to vmtruncate
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3f0a6766e0cc5a577805732e5adb50a585c58175;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

a bug in ramfs_nommu_resize function, passing old size to vmtruncate

It should be pass "newsize" to vmtruncate function to modify the
inode->i_size, while the old size is passed to vmtruncate.

This bug was caught by LTP truncate test case on Blackfin platform.
After it was fixed, the LTP truncate test case passed.
