[PATCH] docs: filesystems: vfs: correct flag name

[PATCH] docs: filesystems: vfs: correct flag name

[Julia Lawall]

There is no flag REMAP_CAN_SHORTEN.  Commit eca3654e3cc7 ("vfs: enable
remap callers that can handle short operations") that introduces this
text also introduces the flag REMAP_FILE_CAN_SHORTEN.  Change the name
in the documentation accordingly.

[PATCH] docs: filesystems: vfs: correct sync_mode flag names

[Julia Lawall]

Change the nonexistent flag names WBC_SYNC_ALL and WBC_SYNC_NONE to
WB_SYNC_ALL and WB_SYNC_NONE, respectively, as used in the code with
wbc->sync_mode.
