Subject: [PATCH] vdso/datapage: Use correct clock mode name in comment
Git-commit: ac84bac4062e7fc24f5e2c61c6a414b2a00a29ad
Patch-mainline: v5.7-rc3
References: bsc#1164648,jsc#SLE-11493
While the explanation for time namespace <-> vdso interactions is very
helpful it uses the wrong name in the comment when describing the clock
mode making grepping a bit annoying.
This seems like an accidental oversight when moving from VCLOCK_TIMENS
to VDSO_CLOCKMODE_TIMENS. It seems that
660fd04f9317 ("lib/vdso: Prepare for time namespace support") misspelled
VCLOCK_TIMENS as VLOCK_TIMENS which explains why it got missed when
VCLOCK_TIMENS became VDSO_CLOCKMODE_TIMENS in
2d6b01bd88cc ("lib/vdso: Move VCLOCK_TIMENS to vdso_clock_modes").
Update the comment to use VDSO_CLOCKMODE_TIMENS.
Fixes: 660fd04f9317 ("lib/vdso: Prepare for time namespace support")
Fixes: 2d6b01bd88cc ("lib/vdso: Move VCLOCK_TIMENS to vdso_clock_modes")
